IMO its pretty useless. Especially for iPhone users, like your example images - because i've texted my normal bunch of mates as a group before, the iphone keeps that message together with the group, and every week if i want to send them a text i just find the last message i sent to them as a group, and their numbers are still there. i suppose it makes sense if you don't have this feature on your phone, but its likely most phones will follow apple and have this feature in the near future. also, more importantly i think, with no details on your homepage about costs, there is no way i'd sign up for something like this. For all i know it could rebill at $9.99 a week or something.
