OK, this hadn't really occurred to me, but if any registered user would like, I can give you a permanent e-mail address of the form [user]@boulderheights.org. I will just forward e-mail to your existing address.
Why you would want this? You change internet providers from time to time, but this would keep your e-mail address the same, provided you don't move, of course.
I can also do boulderheights.us and boulderheights.net...
