Website Team Communication

[robot180]

I was asked to be the team leader of our team's website for the next year. There are a few people helping and I am trying to find an efficient way to communicate so that we don't have to meet (get up and actually leave our computers, lol) and so that we don't have to type, since it takes a long time. We don't all have Yahoo messanger with voice chat, although I might get it if everyone else has it, and not everyone has high speed internet for voice chat and stuff.

Does anyone have any suggestions of ways to communicate over the internet or something so that a bunch of people are in one "chat room" and we can use voice or something to speed up conversation. Most of them have dial-up connections. If you have any ideas, please post them.
