Seperate Log In Page within vB?

[ex-machina]

Hi,

This seems like it could be a really simple hack, but I'm stumped as to how to do it myself since I don't know PHP or vB very well and I'm surprised there isn't one already.

I've had a pretty thorough search, but unless I'm missing something...

I have 3.0.7 and I'm looking to install a seperate log in page that'll look similar to the permission denied page but actually allow users just to log into the forums and then redirects them back to wherever they where when they clicked the Log In link.

I know there's a log in box at the top of all forum pages, but I don't want to use that - I want to integrate the forums over the site and let them handle user registration and thus encourage users entering competitions and the like to post on the forums. So the register link is at the moment nothing more than a register link, but the log in is slightly harder because there's no page to link to. login.php just parses the form, it doesn't have its own.

Any ideas?
