I use to use OpenX back in the days it wad called phpadsnews. It was simple and professional. I tried it recently and saw that the requirements (PHP memory) are out of hand. I'm not keen on their hosted version. I've dabbled with Google ad manager but find it too complex.
I'm using Ad-minister and wp125. They seemed the best for my needs after testing out numerous alternatives. I notice that Ad-minister has a bug in that it doesn't allow you to edit previously created ad's code. Not sure if the dev will update it...
Anyways, is there some plugin that you would all recommend?
I'd like for it to be regularly updated. And also shows me clicks, auto turn off on ending date.
