I'd like to suggest something slightly different. How about posting the actual fics to the AO3, then crossposting headers and links? Whether you want to post the fics there initially or want us to do it, if we use co-authors there are ways to do it and they can be set to be invisible initially and then anonymous until the reveal. It has built in bookmarking, gifting, downloading and reccing features as well as the collections (I was going to ask if I/you could set up a Snapely Holidays collection on there as I know lots of us use it already), and people actually do comment and leave kudos.
I'm already considering it for the Reversathon just to make everyone's life easier, as long as I can keep the silly names somehow ;-)
