Unfortunately, it currently only works in the US, but they say they are working on expanding it to other countries as well. See http://groupme.com/help
So, for any of you within the USA, Puerto Rico, and (maybe?) Canada, if you'd like to join our live "Chatroom" via SMS, let me know. Email me your name (or pseudonym) and your cell phone number. (Note that it's not anonymous. Any member can get the list of other members numbers.)
The SMS Chatroom works similar to an IRC Chatroom. But it's on your phone. All via SMS. You can send #mute if you need to turn it off while in a meeting or something, and send #unmute to turn it back on.
Also, anyone who calls the Chatroom's number automatically initiates a voice Conference Call -- which you can join in with, if / when it's convenient.
Note: If you have a US telephone number -- like thru Google Voice, Skype In, Vonage, MagicJack, or ant other means --- you can Still participate! Even if that number doesn't handle SMS, You Can still participate in the Voice Conference Calling capabilities.
Cool, eh!?
What will they think of next!?
If You want to join, email me or PM me, your handle or name & your USA / PR / Canada phone number.
