Ignore Kanra, she's kind of a dumbass.I use Hamachi, as do quite a few of the dollars members I know around here. We play Minecraft on it, but also some times try to work out online DnD sessions and what not. It's also good as a secondary chat system if you need to get in touch with someone quickly - Since it's not a resource hog like official IM things, and acts more like a localized IRC.
