Account fix from mod, please?

My account developed "forums cancer" with the familiar random six-character tumor appended to my name.

I tried the following, as Joel Cherney (not as "Joel Cherney-TUMOR"):

The reason for this problem is currently unknown. In order to fix this, try the following steps:

1. Log out from the forums completely.
2. Log back in to the forums, but don't select "Remember me".
3. Log out from the forums completely.
4. Log back in to the forums the way you usually do.

Should I try again with my tumor-ized name ("Joel Cherney-u2HtWO") or is this something that only a moderator can fix?

I actually use the things-I've-posted-before list sometimes...
