It looks to me to be pretty much line with the TOS you'd find on other message boards or email group. The clause about rights to republish or resell is generally accepted to mean the permission they need to show (publish) the posts/photos on the board itself. And the reselling refers to the use of our posts/photos as content on this board website when selling ads.
I'm not involved with this board but as a YahooGroups listowner, I've participated in many TOS discussions as they've changed over the tears.
