Suggest you post your request at the following thread.
Forum Extras - adding 'read' tracking by user.
Also, if you want to, you can put in a "feature" request at the bug reporting site. (It is used for feature requests as well as bug reporting.)
Mike's code to add "read" tracking will be great, but that isn't what I am talking about here.
I would like to transform my Recent Activity block in to a Recent Posts block, so that it only shows posts and no other activity. (As far as my courses are concerned it really doesn't make sense to show all users whenever somebody adds to their journal, takes a quiz, or whatever. But, I think it would be nice for users to see what recent posts have been made.)
Anybody know how to do this?
