[General Lee 2: Lee Harder]

Alright, in relation to questions number 4 and 5, there's these three coloured boxes on the very right middle of each post made by each user.
The blue left box is the "like" button, the yellow, pissed on box is the "dislike" button, and the relatively neutral box to the right is the number of users who liked or disliked the post.
Also, for question number 2, assuming you mean the old forums, and not the actual server, it's been stated on the actual enjin forum that it will be kept strictly for nostalgia.
