It's called AIM... or many other easily acquired programs. The chatrooms failed, and an in-site PM system would undoubtedly be abused as well. If you need to talk personally, take it to one of those programs.
Easier said than done, DragonMistress. A lot of the users on this site are young teens on their brother's/sister's/parent's computer and don't have the proper permission to download AIM. AG can make it a lot easier and just make a PM system.
And as for EL_Dyablo, this is an internet forum, not a term paper.
