On the user front, the userbase of SupermanSMS is growing and it's interesting to see that word of mouth is still the best way of marketing.
Thanks to all the friends and family memebers who have been instrumental in popularizing this service. But this is not even the start we have a long long long way to go.
Right a little note about using groups in SupermanSMS.com. So once you have added your contact in the phone book, all you have to do is select the group from drop down menu next to the contact no and that's it you are done.
So in all a phone no/contact can belong to one group and there can 10 groups (G0-G9) which can be used.
Happy SMSCasting
Cheers!!
