We are using vBulletin 4.1.x as a plattform for learning specific things.
What we need is a PER-USER setting to mark a thread as completed. You should be able to enable or disable this for specific sub-forums.
If a user marks a thread as completed it should:
Display an "completed-icon" in FORUMDISPLAY, change the background color of the thread-cell (still in FORUMDISPLAY)
Inside a thread we need a switch to mark it as COMPLETED or to remove the COMPLETED status. This switch should be placed inside the postbit, can be an icon.
As noted this should be a PER-USER setting. So if User A sets Thread 1 to completed it's not yet completed for User B.
It would be great if someone would get points in vBActivity (another popular vB mod) whenever he marks a thread as completed. Documentation is available, should be just a few lines of code as vBActivity is designed to be integrated in other mods.
It is comfortable to work with us, fast response times and we pay fast & fair.
