It's not me having an issue with this, but rather a user on my forum. No one else has actually reported the issue and I'm not sure as to exactly what is going on. Here's a quote as to what he said on my forum:
I've found that quite often now when I'm trying to type out a response to something someone has said in various forum topics that when I go to submit the response I've tried to make, the system has in the mean time gone and automatically logged me out (usually within 5 - 10 minutes of hitting the 'Post Reply' button, though it has on occassion done it in as little as three minutes too). And when I go through the procedure of logging in again and I get returned to the page I was typing my response onto, all my work has been dutifully erased by the system and I have to start over from scratch. This last happened on the Donations forum when I was commenting on looking into pricing for my own server.
I'm not sure what's going on or anything, so this is quite new to me. It seems as though he's the only one affected by this, and I don't know whether or not it could be cookies/cache or what.. I don't know what other information I can provide other than this right now.
