Certain number of thread views, until guest are forced to sign up
sometimes i see many guests, people that jsut come and read... and blah....
i wonder if theres anyone that would make a hack, that would limit a guest of seeing threads after a certain amount. So lets say after 3-5 threadsviewed, they are forced to sign up.
this is a good hack, i planned to do this to do this with a few pages on my site, however with threads you wouldn't really wanna alienate search engines.
