Well I'm kinda crazy about keeping track :) What I tend to do during fests is create a "private" LJ entry where I keep notes on the fics, and continually update it until the fest is over and I'm ready to post. Then I C&P the HTML from the private entry into a "new" public post and post it fresh. That's what I did for this one - every week after voting I'd come back to the post and add in my choice that week so I wouldn't forget :)

But I feel you on thinking I was jinxing my favorites - it was so rare that the one I voted for ended up winning ♥
