Ah... no I didn't mean editing posts.
That choice is probably in reference to "locking someone in" to what they say.
I am actually talking about just constructing your first draft.
I have found if it takes more than 10 minutes for me to type in this box, odds are high that when I hit 'Submit Reply', my stuff is lost and I am asked to sign in again and I basically have to type it again.

I have heard at least 2 guys say this frustration with getting timed out caused them to give up on posting to the forum.
One guy in particular would be a valuable asset on here.
I would guess we have a 10 minute limit on how long we are given to type up a post, "or lose it".

Maybe different permissions in user groups have different time lengths.
You have made some pretty detailed posts, Rick. Have you never been timed out?

Maybe it's our choice under preferences or something? I will investigate as well.
