database integration

[jrwap]

I just installed a new script that works as a yahoo style directory. In order for some one to add a site, they need to fill in a valid emal address and username which is then saved in a database. I would like them to have to be a member in order for them to post. How can I do this?

I would like the add part of the script to check to see if they are a member, and send their username and password from vbulletin to the database for the directory. That way they can simply use their site wide user name and password to add more sites or edit them in the future.

Thanks,
