Your friendly tech here again letting you know that I finally tracked down a bug in some 3rd-party code we're using to tie the forum together with the site and fixed the "you get randomly logged out" bug. Needless to say it was a huge pain for me and for others too I imagine.
Let's keep our fingers crossed, I think I finally squashed it for good! I'm going to be so embarassed if I get logged out after I submit this post! =D
