I suspect there's a suggestion (haven't checked) but no, right now there is no option to easily find your drafts. I have actually stumbled upon ones I thought I had either posted or deleted. There's a limit on how many days they are kept, too, though I can't remember the number just now.
I've been writing a post for days but I had a lot of work and I left it 5 days. Today, when I wanted to continue it i entered in the forum section and... nothing. It dissapeared.
