Crisis mostly averted; I've managed to recover pretty much everything that was stored at thumperworks.com and have notified almost everyone I need to about the change of email address (I think. I hope.) I can now let the domain disappear into cyberspace, where a good friend pointed out that it will be snapped up and used to sell sex toys.
Consider that my contribution to society.
I will now save $15/month in hosting fees. Yay!
...and I'm still a drag king. I am! I am!
