    Hey Tim, there are a lot of changes so I've been hoping a few people will help with some extended testing before I release it - University of Canberra and Howard Miller have already been doing some testing - I'd like to hear from anyone that is able to test group submissions well too.

    Hi Dan, at some point would it be possible to place the % score in a separate column in the grading table so it could be sorted to highlight papers that needed attention?

    Hi Mike - could be a challenge there, I don't believe there are any plugins that push multiple "grade" items into the gradebook. The similarity score is not designed as a "Grade" and is really supporting information that should be used when a teacher is grading - which is usually done on the activity modules own grading page. The only exception to this would be the forum activity but there are other pieces of development under way that could add a grading page to the forum activity in future - see MDL-31860 for more info on this. Although I understand having the information in the grade report might be useful, I'm not convinced that it is the right place to put this as it should not be used as a "grade"

    thanks Dan, yes you might be right. I was thinking that it could perhaps be pushed to mod/assign/view.php gradingtable.php as an extra column in a similar way to the assignment feedback plugins. Perhaps thinking of the similarity score more as part of potential "feedback" rather than as a "grade"? anyway, just a thought after seeing an academic try to use it with a large class - many of the other columns are sortable in the table and he mentioned how much easier it would be to quickly scan for the submissions to have a further look at.

    Yes - I've thought about sorting before, unfortunately the way the assignment table is generated there isn't an easy way to influence the order based on plagiarism scores. Especially when a student submits more than one file which generates a report - it displays the assignments per-user rather than per-file. I guess we could write a custom report/page that displayed all submissions for a particular activity that had a score higher than a certain value but you would still need to perform the grading on the main page. In fact - rather than writing a custom report you could potentially use the configurable reports block (or similar) to run a report with the information if your organisation will allow you to use the sql-based reporting tools.

    HI Dan, thanks, yes I can see how it could be an issue. Never mind... for now smile We do use config reports and I did write up a quick report for him but it was more about ease of use and quick scanning in a v large class in the grading form.

    Hi Dan, we have commit installed - 14 Jan.

    with the admin settings we had urkund enabled for all course module types but no longer want it enabled for forum, advanced forum or workshop. For existing instances of the modules, if the admin setting is set to no for then the course module settings do not display, so staff cannot switch urkund off for individual items. We can leave it enabled and advise to remove for each forum, but I wonder if there should be more granular settings for each module type in the admin settings? We want to make it enabled by default and switched on for assignment and optional but still enabled for the others eg

    Enabled for Assign, Urkund Defaults: Yes (urkund form appears in module),
    Enabled for Forum, Urkund Defaults: No (urkund form appears in module),
    Disabled for workshop (defaults to no, urkund form does not appear in module) etc.

    Make sense?

    Hi Mike, makes sense and I understand it would be useful. If you have someone internally that can make the changes and file a pull request I can merge it with the current code-base - alternatively make sure you let Urkund know about your feature request and they might add it to the next piece of feature work they get me to work on. Thanks!

    No worries Dan, we have done some basic changes involving setting the module form to appear at all times, but using the enable activity control on the first tab to set the default setting to Y or N. Perhaps only solves our use case though... will revisit next week and file a pull request when it's ready.

    Seeking a little help here -- the plugin has been installed and activated. When an editingteacher sets up an assignment, it shows up as a option "URKUND plagiarism plugin' for the assignment activity set up. However, the 'Receiver address' box is grayed out and has an 'X' to the right of the box. I do not think I have set this as a default and locked it anywhere so I am not sure why this is the case. Without this, although the editingteacher is ok to set up the assignment, and a student is able to submit an assignment, it never gets checked (submitted to urkund). It shows up in the URKUND plugin Debugging tab as a status '444'. There, if I click on resubmit, it shows the error: "URKUND fileid:1 sending to URKUND ERROR: no receiver address found for this cm: 8 Skipping file". Any suggestions?

    Hi Dan and others, I am prodded to upgrade to the plugin version 3.2.3 our site being Moodle 3.0. However, I wonder if that plugin version will work with PHP 5.4.16, since supported software lists PHP 5.6.

    Hi Paul,

    it should work but I don't do any testing on PHP 5.4 myself. I have just added PHP 5.4 and 5.5 to the automated travis-ci checks on the urkund repo (I had previously removed them to speed up the tests) Let me know if you have any issues though. You can see the results of the travis tests here:
