Tagga may be a great resource for your GOP state party or campaign.  Tagga, a Canadian company based out of Vancouver (home of flickr), appears to be a great little tool with a lot of potential.  Tagga enables you to establish text messaging accounts for free and you can create a personalized code.  I just set up an account for the Massachusetts Republican Party and you can now text MassGOP to 82442 to join massGOPmobie.  I will also set up a RSS feed to our blog, MassRoots, where people can get updates from the blog on the go.

You can send up to 80 characters to your subscribers for free, paying $0.20 a text will give you 120 characters per message.

Soon, you will be able to create polls where people can vote from their phones and newsletters where you an create text message newsletters.  Granted, with Twitter you can update volunteers on their phones but this is a nice tool with a specific niche that people can understand immediately, there seems to be a learning curve with twitter and "tweets."  

I hope to roll out the new MassGOP.com in a few days and this will be a nice addition to the site, I'm glad I found it.  Speaking of which, I'm using the new and improved websat created by Cyrus at the RNC for the new MassGOP.com and it's been a great system - if you're with a state party, I highly recommend it.
