The back button only works if you *start* at the main page.... I never do, I have a bookmark that takes me straight to the forum. If I want to view the main site page, as in
http://www.rcmodelreviews.com, I have to swipe and delete the */forum/xxxxxxxxx with xxx being wherever it is I am at the moment, in the address window of my browser. I can't say it's much of a problem for me, but it does irk me that you only get a clickable link to the "Board index" and not to the main home page of RCMR. I'm not sure if it's a big chore to do in phpbb, but I think I'd rather have Bruce work on his next review/video for now.
