So we are getting there only final adjustments ...
Two things I couldn't figure out...
1. Is there a way to configure the RSS Item Title with a pattern or to show at least the conent of a field (similar to the moodle activity "database")- e. g. # #timecreated:date# # and [ [ title] ]?
2. We want our student to admit only one entry so we set Maximum Entries to 1. We got a "new entry"-view. The limitation works perfectly - but is there a possibily to prevent a student to go to the new entry form after he made his entry - or at least give them a hint when he/she tries to save another entry (at the moment it's not saved but the user is not aware of it as the form is just there so he could leave and think that his second entry is saved). At the moment we do include a permanent message above the form. Or do you have an idea of a better setup?
