Don't worry, I don't use that silly ignore function, but that doesn't mean my ignorant yet overloaded brain is paying attention to every move on amiga.org, it actually happens I actually miss a post or two! 
The thing is I have a feeling I'm only being logged out whenever I'm making posts, not when just browsing. But anyways, thanks for the tip. I'll try that! 
Wow... I can understand why you get logged out, I watched as you typed that post, it took you over 9 minutes to type it (I almost dozed off)...
Nah... seriously though I had noticed this problem myself last year when playing games in the arcade section on to discover after about 15 to 20 minutes of playing and finally achieving a high score, when the game ended and you were meant to be taken to the high score table to enter your name you would find instead you had been logged out and your high score was lost forever...
After a quick grumble to Karlos I discovered that button in the top right and now I never get logged out unless I do so myself, saves a lot of frustration like you say when typing a long post only to find you've been logged out while typing it and it's gone forever...
It would help folk if there was some text beside the button like "keep me logged in" as I think most folk think it has something to do with registering due to it's current position...
