In this same vein, would you recommend running them as islands or putting them in each forum, etc.
Also, toying with the idea of having those who "donate" to the site's upkeep don't have to see the ads, so would the subcription option be a good way to do this....and with that, do I need to mod my forums to do a group check or whatever to know if the ad should be displayed or not.
Definitely keen to hear some options and suggestions around ad placement, straddling the fine line between pissing your user base off and getting decent revenue to support the site.
