I don't believe so, and I don't think your ability to log in is affected if your email is defunct or made up. I'm made up a few myself ,lol.

of course, that's if that's what your problem is... why do you ask?

If you email Ryan he can probably change that for you.

I ask just because I only found out about xsketch when I checked my ancient, dead email address as I do every so often... It's no big deal, probably. I'll contact Ryan when I have the time, heh
