Sucks you guys have been having a problem getting mail to AOL users, in that regard I feel for you guys.
But come on! Ever since Prodigy fell off the radar and Compuserve and AOL rose up, AOL was always called America Off Line and not without reason. I could never figure out how AOL managed to get so much revenue and become such a major ISP. But the reality is your average AOL user is an old person and they just don't expect anything better from the internet because they never had anything else to compare AOL with. Why do you think AOL can get away with their crappy Java Hijack of your browser with their "improved" browser? Because there users do not even know how to use their default browser. To illustrate how bad their users are: I did some tech suppt for FAFSA on the Web while in college. I would have to tell AOL users to connect to the net then open a new and seperate browser. Seven out of ten could not comprehend this concept. Even the highschool and college aged ones.
Those that go to AOL for the email and chat client are really no better off. There are other clients out there far more stable, and other free email systems that work 100% better which do not give you the designation of @aol.com so all your friends can laugh at you.
