Hello, I am opening up a classifieds website for my local area and I want to know if it is okay to use other ads along with google adsense, for example. Could I post date.com and flowerdelivery.com banners on my website as advertisements near the google adsense ads? Also, I know some content is not allowed with google adsense, what kind of things should I watch for in peoples postings on the classifieds site? Thanks
