I bookmark the forum (not the home web site), open that URL, and it remembers me. I only have to log in if I've been off fo a week or so, or if my IP address changes from the last time I logged in, which happens periodically when you don't pay for a fixed IP address. And when this occurs, my computer remembers my user name and password so I don't have to.

I'm using a real computer and Firefox. Life on a phone might be different. I'm the only one using this computer (unless someone breaks into my house and steals it) so I'm not concerned with kids or a wife discovering where I play and kibitz, but if you're sharing a computer, you probably want the security of having to log in each time.
