Understandable! I've been finding that I'm wasting the time anyway texting or GChatting other RPers, since I can't have AIM at work, so Slack seemed like it might be a good alternative
It's kind of a little darling in the tech industry right now, all the major tech companies use it for their team communication. You can use it in the browser, or a desktop client, or a mobile app.
midcirclenine: Oh, is there? I didn't know about that--it's surprisingly hard to search for existing Slack channels. Any chance you know who runs it/who to ask for an invite?
