Haha, we also have a UB banner on the bottom of every page loaded in the werkz forum. I had a nice long talk with Noodles, and we discussed it being the information, not the money, so we went through with a link exchange. We're already gotten a few members out of this deal and quite a few hits (and most of our members are also members there anyway, so it's not changing much). It's helping us more than it's helping them, but sshhh.
haha, it's only for a short while though.
Edit: and they're not a "sponsor", it's just a link swap.
