[htc evo 4g]

Has anyone heard of the app groupme where your able to have all your messages grouped in a chatroom format? groupme.com for anyone that wants to know more. My question is I cant seem to get the confirmation code sent to my phone (Galaxy S3) so i can type the code in on my tablet. Has anyone had any luck getting groupme to work for them for those that use this app?


thanks
