Do you use FireFox? If so, there's an extension called which I use to auto refresh a spare tab with the forum index page opened. Just leave that tab running while you write your posts in another tab and you'll stay logged in. Another thing I always do just in case is select all and copy BEFORE I hit reply. Then, if I need to log back in for any reason, I can just paste the text. "Reload Every" has pretty much eliminated my log out issues though.
I _never_ write longish text in a web frontend. I use Notepad, Notepad++ or whatever, then paste into the web front end when done. Simple, straightforward, safe, compatible with any brwoser. El-Rallef
