The link ("Advertise here") is right there under the banner, which is a logical place for it. So one click away if you're already in a thread, or two clicks if you're on the main page and need to click a thread first.
Not straightforward enough if I keep getting inquiries about advertising.
But whether the forum could use more banners is another story... I would imagine more users would start using the "Disable ads" option so it might defeat the purpose.
Most users don't have that option and it could always be taken away.
I think people would miss that one as well. The reason I suggest top is it's far more prominent at the top and will probably be the first thing you see. Theymos seems to be fairly against more advertising though, but I think a banner ad at the top would be less intrusive or annoying than signatures which the forum receives nothing monetarily from.
That's exactly why I suggested a banner at the bottom of the page. I don't think signatures are going away seeing theymos' past posts on this topic.
Yeah, same. Auctions is probably one of the last places someone would go to. I know a few of us have received requests to buy sticked threads/promoted posts as well.
Yes, I get that too equally often.
