i bought a social network/forum script and am now live with it. during my first week launch i used twitter to get sign ups. i have 250 - launched 2 weeks ago. signs ups have died down to about 5 a day now. still pushing twitter but not much is coming from it. any ideas on how i can get people to my new site? inexpensive ways or free ways to get the word out about it? SEO for the script is pretty weak so i am not sure how well that is goingto work.
