I promise not to ask again, but how do I select the "Chatter" forum? The choices that I see in the Forum drop down are:

Internet
Linux
Microsoft SQL Server
Perl
PowerBuilder
Thin Client
Visual Basic and VB.Net
Visual C++ and C#
Visual Foxpro
Window 95/98/ME/Nt/2K/XP

I don't see "Chatter" listed as a possible selection under "Forum". What am I doing wrong?
