Just so you're aware, TXTMob is historically the name of a famous-in-very-small-circles group SMS service from 2004. Released as an activist digital art project and used to organize protests, it's often cited as one of the original influences for Twitter. It's not a name that the average person on the street would recognize - and fortunately TXT won't be confused with Text by search engines - but it's worth being aware of it. (Unless you did it intentionally, in which case, love the shout-out. :) )<p><a href="http://en.wikipedia.org/wiki/TXTMob" rel="nofollow">http://en.wikipedia.org/wiki/TXTMob</a>
Wow - I like this a lot. A very simple idea that's actually useful! How long did this take to create? Aside from Twilio and GroupMe what are you using to power it behind the scenes?<p>One note - if you're going to have people turn over their phone numbers to you - its probably best to include a privacy policy of some sort that explains how they will (or won't) be used.
