Forum - activity timer logs out?

Howdy all!
Was trying to create a post this morning while logged in. As I was working on the post stepped away to finish breakfast and when I came back to finish the post hit POST, got a notice that I was logged out.
This has occurred twice.
Is there a setting I cannot find to keep me logged in?

Thanks!

Hello,

That's a painful situation. Look for a checkbox for "remember me" near the sign in credentials. You won't be automatically logged out as long as that box remains checked.
