TextMob – Create SMS Groups Around an Event or Trip
http://www.textmob.co/

Textmob started from a small trip to Tahoe. 100 inches of snow had fallen at Squaw and Presidents Day Weekend was fast approaching. He knew many friends were planning on going to the mountain, but didn’t know where they would be or their plans. A few friends had setup Groupme groups that have worked well, but would need everyone’s phone number to enter them into a group. He just wanted a simple RSVP webpage that also entered the submitter into an SMS group. The members could organize through SMS before the trip, coordinate during the trip, and share stories after. In a few hours he made a single page to do this. After the page was created many friends approached him saying they wanted a similar page for a reunion/wedding/trip approaching. He figured that he would just make a scalable app to do it. Textmob was born. This has been added to the tools section of Research Resources Subject Tracer™ Information Blog.
