So it turns out email from the TLHH server has been broken for a while. No PM notifications but the worst part is you can't reset your password. I dug around for an hour or two trying to fix it in the backend but the forum software is hopelessly outdated (2007, woohoo!) and not cooperating with me. So for now it's going to remain broken until I'm motivated to hack at it again.
Password reset requests will have to be handled manually.
If there's an urgent site issue, feel free to email me. I don't log in often to check PMs but I will be more responsive to emails now than I have been for the last... decade?
