All I'm getting is a blank window/tab when I click this while in "Edit My Profile"...
Also...is there a way to change your username? I goofed and left off the "h" at the end of my user name. Can't seem to find a place to fix it (if you even can)...Hopefully it's on the currently blank "Change My Preferences" page. Or maybe I'm blind and didn't see the option under my Profile.
If it can't be done....how can I cancel membership and start over?

Thanks for the catch! The prefs page should be working now. We also fixed your username (as you can probably see).

Excellent. Thanks for the fix!!! I sent a comment earlier this morning. Please disregard.
THANKS again!
