>>14 i wish i'd never watched school days now...

currently watching S.A, it's pretty good.
Shuffle! is another good one, nice mix of tragic backstory, supernatural (although not so much that it detracts from the main purpose of the anime - romance) and school life. nice characters and visuals too.
Tokimeki Memorial might be worth a look too, it's a fairly nice, lighthearted anime.

>>19 i found Air to be a bit confusing, but the visuals are stunning.

oh and stay away from Green Green. from the short intro i read about it, there was plently of opportunites for multiple romance scenarios... but they just spent the whole series doing jokey ecchi scenes. waste o' bandwidth if u ask me
