It's a slippery slope! I don't see a problem with ads (and not just b/c I block most of them w/ my hosts file... ;-) but ads for what, and is schoolforge set w/ its non-profit tax exemption, etc. The rotating banner sounds good to me.After considering some of these ideas, and about ways that SchoolForge could bring people in, and if there were a banner system that promoted member efforts, would the idea of a sort of voluntary co-op for ads to be presented on larger networks be desirable? That led me to think, well, instead of chipping in to get advertising, maybe that would be a good reason to allow some advertisements on the website - it could go into a pool that would be used to further promote member efforts. Hmmm..
