Yes, you do get used to logging in; it becomes habit. You'll get mad that day when you dont have to log in so often, that day that will never come. You'll love it so bad. Or the same for when you forget your password; Maybe you enjoy typing your password: tnl tab iyamagollldenngawdd enter. You log in so many times, you're likely to never forget :)

Eventually, if you ever learn that you always idle too long while trying to prepare a forum post, you will fix your habitual mistake and type posts in your text editor, and without hesitation re-login in another browser tab/(window?) before posting.

Or you can be like me and iteratively refine your post w/ the handy edit function, at the same time resetting your timeout.
