Need advise

[deem0n]

Hi!

I'm newbee in vb programming.

I need make this task:

we have system where vb is subsystem.
vb_users synchronised with systems users.

system users have level which limit access to read content.
levels look like:
Bronze
Silver
Gold
they's rights are hiearchial ( means: Gold have access to content of silver and bronze level)

I need implement this into forum.

So each forum will has level and each user.

if user try open forum with level bigger then he have , he will get notify page and no accsess to this forum.

Please, give advise how make it simpliest and/or best way.

I think about custom permision but it need showtreads.php change.
Just suppose the way,please
