good sites. i didn't know either.

buy stickers that has your logo on it and pass them out or sticker them around towns. then you will be in front of everyone all the time!

like you said, people do love free. but if it is a lame free item. no one will want it.

i think you should give as many people that sign up in one month a free month of memberhip. Then at the end of 30 days they have to renew for a fee. then they will have a chance to be hooked on it...
