Wondering if we can figure out why this is, and fix it. As long as I have the website open in a tab, I shouldn't get logged out automatically, but it's happened to me twice, even while posting a reply. I left the tab open while I did something with images, and when I came back and tried to post it, I was thrown into the main forum area and a box that said "you are not allowed to access this area" popped up, and I realized that I had been logged out.
Also, the ability to stay logged in would be good too. A checkbox under the login section is the norm. :)
