i want to make it where to access downloads from my site the person has to first be registered in the forum....when the person goes to download a pop up box will ask for his info and he would put in his forum log on info....i saw @ another site and the guy told me this is who they do it:

As far as downloading, we're using mod_auth_mysql with apache 1.3
hitting against the messageboard database (mysql) for password

Can some advise me how i can do this on my site
