Auto loggout is really, really unnecessary

I've been a forum member for less than 24 hours and already three times I have lost comments or edits due to a combination of this sites automatic login process (as if it's a bank) and the fact that the back button will not retrieve the page that I was on before hitting the post button. If we could go back we could retrieve the comment contents, login and paste it. Or maybe there is a setting I don't know about to turn auto logout off… I have a lot of security on my system, I don't need this facility at all and it's frustrating when I forget to copy all my comment before hitting post. You don't get any indication you've been signed out either so it's a real trap.

I haven't had to login here since I purposefully logged out in January. What Marilynne said.

The main cause for logon issues that I've seen is when trying to access the site via Nikon News - Nikonites - Nikon Community & Forum instead of just nikonites.com. The login cookie is specific to the non-www version of the site. Hitting the correct url and setting the "remember me" check box has kept me logging in for awhile (months).
