hiding a forums based on conditional

[AsscBB]

Hey all,

Well after a brief hiatus from setting up my board, I've gotten back into it and run into a bit of a problem. I have set up a table which mimicks usergroups to segregate my users into different categories since the default usergroups did not meet my needs. Now, I want to use this table to drive wether or not to hide a forum. Basically, selectivly show forums based on my custom table. I think this would be a simple hack adding an if statement around the forum code, but I don't know which file this is in. Can someone point me in the right direction? I'm still learning MySQL and PHP, but I'm more than proficient in VB - which in short means the syntax still throws me a curve every now and then and tracing things across the files can be quite daunting!

I appreciate any help!

Scott
