I started writing everything down in a loose-leaf binder when I joined my first swap in September. I know myself well enough to know I need a place to keep track of not only my partner's name & address & deadline, but what I'm sending, what day I'm sending it, tracking number etc. (Afraid I'll lose that tracking number if it's not written down!) Also, I write down who sent me what. It works well for me, although it doesn't prevent me from getting confused from time to time!
