It seems to be a version for phones without touch screen. It has numbers next to some links, which I suppose are the buttons need to press to click the link. There are links without numbers, though. How do you click those if you're on a phone without touch screen? Do you use the arrow keys?
Other differences are that there're only 9 topics per page in the board and 5 posts per page in the topic.
I wrote this in that mode (see icon above!).
