Sent a test message to my small group of family members via text messaging and it worked, once you go to the TweetParty site, log in and then sync your followers, form a group and then click on manage. a list of your followers will come up and you can then click ADD. make sure to follow tweetparty and to sync you phone, let me know if anyone can make a group and do this, the possibilities with Twitter are unlimited and the number of third party apps available is also AMAZING!!
to text to your group
send to 40404
