Hum... it seems to me that if you want to sell more where you should really start is updating your wwwthreads info at script pages such as cgi.resourceindex.com, hotscripts.com, and tons of others... not very trusting forum when you see it hasnt been updated the last couple years...
Scream, I´d take some time and go update/add wwwthreads info on all scriptpages you can... every time you make an upgrade release, even if it is beta... you will sell literally 3-5 times more.
