Unfortunately, that doesn't seem to work. I've selected 'remember me' when logging in, but when I later try to access a bookmarked forum during a new browser session, I end up on a page titled "Sorry, we can't find that!" followed by a statement that I don't have permission to view that forum, and that I should log in.
The old system had a 'log me in automatically' setting that worked like a charm, taking me straight to the requested page.
Any other suggestions?
