If there is a button I use more than any other, it is the "View new posts" option. I assume this is the same for others.
Taking a lead from the Scooterotica forum, where clicking on the logo takes you to the board index, could our forum champions (hello Paul) take this a stage further and alter the forum so when you click on the LCGB logo, it refreshes the "view new posts" page?
Just a thought.
