i agree with you guys completely about them not having much to argue about.
when i saw the post on their site, the first place i went to was paypal and i didn't come across any button that looked just like this, but then i knew they had it set up for exactly the same purpose that we do here, so i didn't think there would be any problems.
i also personally know the guy who wrote the code for their board, and he does tend to go a little sensitive regarding that website.
i don't think we have anything to worry about except for the wording of the FAQ. after reviewing it, it is almost word-for-word in some places.
