Textuary.org This is an website that provides a way to send sms messages. It uses Plivo api, so it is going to be very stable. User logs in and is given a number, which costs me 80 cents per month. i couldn't figure out how to solve this issue because if you share numbers, then when people reply to the sms we don't know who to route it to. So the solution is to give everyone their own number, but I was just thinking that could be combined with asking user upon signup if they are going to be a regular user or if its one time. And this could be adjusted based on watching. Regular users need dedicated number, but we ought to be able to recycle some number before the month is up, so not to waste the 80 cents on a one-time thing. Or, Could we have an anonymous throw away one-way sms and then for two way, login??? There we go, I think that's it. People that are going to use anonymous, just don't login, and we will allow you to send one way -- maybe not a great idea for security?
