I don't know what character you're talking about, but old characters are sometimes cleared out. If you create a new character, you'll be able to log on and see how the game's looking these days. I hope that last player works for level 1.. but you may have to get a couple levels first. Type 'last player <you>' and you'll be able to see if it's the character you remember
After that, you can page the gods, who may be online to help you.
If that doesn't work, an e-mail to
coders@slothmud.org will almost certainly be seen by Kj by tomorrow when he runs his Christmas quest. And if he can't reset your password, no one can
Good luck.
