EDIT: I'm aiming to do this on Sunday, December 14th, 2014, at around 1200 EST, which is around 0900 PST, and 1700 GMT.
Last time we had to update, it took less than an hour, and things went pretty smoothly. All posts will be backed up, and I'll announce it if there are any problems.
I've been seeing a lot of instances of PMs failing to send or be received lately throughout the board. I'm putting in an inquiry to my host as we speak. I'm hoping the forum upgrade will take care of this.
Please let me know if you guys have trouble posting!
Sorry for the inconvenience!
