Honestly,
We don't want a token from them in return, all we need is a success or failure code to know it's a valid user/pass combo. Would gladly be willing to meet with and sign an agreement with whoever is in charge of Bitcoin forum.
Any information on who I could contact would be greatly appreciated as well.
Thank you again.

You could do what you are contemplating with the method I suggested. You could do this without any agreement or code or anything from the BitcoinTalk.org team using only the publicly available information freely divulged by its users, and without BitcoinTalk implementing any change whatsoever. You can progress this immediately with nothing you don't already have.
My suggestion also allows your system to remain uncompromised by any security issues which may or may not exist in the BitcoinTalk forum.
If you insist on barking up the OAuth tree, you can directly harass the folks in charge with offers of Agreements and Contracts by clicking on that "Donate" link up there and reading enough of that page to see who has the keys to cage, or by a quick reddit search. (Hint: Its not really Thermos) Or failing that, sort the members list by date registered and see if you find anything interesting.
But now that you've given me the idea this is somehow desirable, I (or someone with more copious spare time) may code this together and sell it to you instead.
Why not simply offer a bounty?
