Well I had a little more trouble with AIM. I accidentally put in my email address as my screen name and have quickly discovered that master screen names, which apparently is the first one you sign up with, cannot be deleted or changed. Other than this mistake, signing up for aim was quick and easy. I don't really know anyone's screen name on AIM but I will soon. This can definitely be used for work. In a large office area, instead of walking over to someone or calling them, you could quickly send a person a quick IM question. I liked that AIM even had a c0-workers tab. I have never used aim before but have used ICQ and others. Thanks for reading.
