The Delphi forums were very convenient for me... I already have an account there, and I just had to choose the school forums from the 'My Folders' option. Now, I'll need to take yet another step to do things.
The Forum brought some surprises to me in the recent past: I heard from a student who graduated the year before me. Said student and I had... well, a colorful past not full of warm fuzzy memories. I'll have to wonder how many people will come to Classmates now.
