Configuring SMSsend?

I just discovered this handy-dandy little function in Kopete and decided to try it out. I downloaded and installed SMSsend through YAST, but I can’t figure out what I need to do to add an account in Kopete, or what to do in the first place. I don’t know if I need to go to some website to make an account or what. I can add the account in Kopete, I just don’t know what to put in (other than my provider, Verizon) to make it work, and I can’t find a website for it or anything. Anyone know how this works?
