Hey,
maybe it's already possible, but in that case it's too well hidden for me :P I'd like to mark events as interesing, without having to atend them... Jut like int the Classifieds section.
I'm sure you have better things to do at Christmas and that you have enough projects anyhow, but just as an idea for a rainy Sunday afternoon or so ;)
Cheers and thanks for the work you do on the site!
