Getting back into refereeing after about five years off...

[wonderlic]

Hey there everybody, I have really enjoyed reading the posts here and all the discussion. My question is this, I have been out of officiating for about five years and will be getting back into it shortly (after the adjustment of moving to a new city) and was wondering if there have been any major rule changes in the game. I have been going to as many games (high school level) as possible to "relearn the game" and can't wait to get back into it. Any help would be greatly appreciated. Thanks
