Ah, sorry, I didn't explain properly. I'm having a problem with my Technicpack.net account, not my forum account.
Also, I have no idea how to move threads.
I've recently changed my email and have been going through updating my accounts. Unfortunately, Technic doesn't have any update email settings that I've found, and there are no contact emails either, so if someone could either point me in the right direction or change my email manually, I'd appreciate it.
