I have both, MSN messenger, and Yahoo messenger. I know that some of you have been calling each other with working on the club and such, and it does add up on one's phone bill. So my suggestion is that if you have these and a michrophone for your computer, that you could save on the phone bills and talk thru IM's. From experience, I know that the one that works better is Yahoo's if you want to talk, for some reason it is alot clearer sounding. This is just a suggestion, and I think that you can talk to more than one person at a time. If you click on my nic here, my information is there for either. Keith
