This is a very nice and comprehensive addon and a no-brainer for those who want to show/sell ads on their page. Siropu also responds quickly when asking him questions, and my highest recommendation :) :)
Fills in a feature of XenForo I was surprised was missing, and this addon not only fills that need but enhances it with some extra customization options that may not have made it into a core feature anyway. So a win-win all around, plus has an active developer who maintains the addon. Highly recommended!
