This problem has likely been noticed before, but I can't recall seeing it discussed, so here goes.
There's a link to this site at the very bottom of the page in the PBW main forums. I find that when I arrive here by that link, my login won't work.
The first time this happened, I thought maybe I made some bad keystrokes or something. So today, after visiting the PBW Forums, I tried the link again, and was again unable to log in. I had to reenter from another link. For all I know this topic may already have been beaten to death in another thread, but I thought I'd post it just in case.
