Can't remember my Minecraft email?

I recently got a new computer and when trying to log into minecraft and I can't remember the email I used when starting. I remember my username and what password I would have used I just can't remember the email. Is there a way to figure it out?

Neat blog! Is your theme custom made or did you download it from somewhere? A theme like yours with a few simple tweeks would really make my blog jump out. Please let me know where you got your design.
