We havent used vbulletin in a couple years and we recently purchased a 3.0 license for a new project. In the past we always used phpadsnew but since we have been out of it for so long we wanted to see what the best solution is at this time. Here is a breakdown of our needs and current situation:
We will be installing the vbadvanced hack so that we can have a homepage.
We need to be able to implement all different size banners, in many different locations
We need good statistics & tracking
We need the ability to place an ad in only a certain forum
We need the ability to have a "sponsor" for a forum where that sponsors ad will appear on the forum homepage with that forum, as well as the forum display page.
We need to be able to use both regular ads and html ads (code form external affiliate programs)
That is about the extent of it. If the answer is still phpadsnew, please let us know what is needed to integrate it with vb 3. I honestly dont even remember what we had to do to make it work with 2.x
