What do you guys recommend? I work in a small office where it would be useful to have an open chat window all day long so we can communicate with each other. I don't want to use the traditional clients such as AIM, Yahoo!, etc. because those are primarily for one-to-one messaging and group chats take too long to set up and log in to. Ideally I'd find something similar to g-chat but 6-way, so everyone can see everything everyone says. I've downloaded a few from download.com but haven't installed them yet. Thanks for your input!
