I have noticed a few members mentioning that they typed up a long post only to have it "lost" when they clicked to submit

the system automatically times out after a default period when you are logged in but what it sees as "inactive" which can be while typing a lengthy post

the way to avoid losing the post to timeout is to check the "remember me" option when you log in. that doesnt seem to time one out on longer posts.

some members also prefer to keep a word document open when typing a longer post and first draft it there and when satisfied, copy and paste it to your posting box here and submit

hope that helps for those frustrated by those time outs
