There's a sticky at the top of the Boards called "abbreviations"...the lingo does take a while to figure out...here's what I can think of:
ROFR is "right of first refusal"...it means Disney has the option to buy a contract that is for sale, for the terms the buyer and seller have agreed to. Disney hasn't been exercising its ROFR rights very much lately--but they can. If they do, the seller sells the contract back to Disney and the buyer gets his deposit back, but has to start over in finding a contract to buy.
DVD is Disney Vacation Development--it's the company that owns DVC.
The DVC resorts are OKW (Old Key West), BCV (Beach Club Villas), BWV (Boardwalk Villas), AKV (Animal Kingdom Villas), WLV (Wilderness Lodge Villas), BLT (Bay Lake Towers--the DVC connected to the Contemporary), SSR (Saratoga Springs Resort), HH (Hilton Head), VB (Vero Beach), and GCV (Grand Californian Villas--at
Disneyland in CA). There's also a new DVC in Hawaii, usually referred to as Aulani.
MFs are maintenance fees--they vary by resort, but range from just below $5 per point to almost $7 per point. (Actually, I think BLT may be right around $4 per point). They are payable yearly, in January (or you can have them automatically deducted from a checking account, at no extra cost, on a monthly basis). MFs last for the life of the contract and you must pay them each year whether or not you use your points.
UY is use year (sometimes called use month, altho I've seen anyone use "UM")...that is the month (the first of the month) when you will get your year's allocation of points. (i.e., if you buy 200 points, you'll get 200 points each year for the life of the contract, on the first day of your UY (or use month). For example, my UY is Feb. So each Feb. 1, I get a new allocation of points.
DDP or DP is
Disney Dining Plan (or dining plan)...
ME is Magical Express--the free motor coach service that will bring you from Orlando airport and take you back there (it only goes to MCO--the Orlando airport, and it's not restricted to DVC trips--any on-site resort guest can use it).
There's an airport check-in desk at each Disney resort that has its own acronym too, but I can't think of it at the moment.
MS is Member Services, the place you call to make DVC reservations (and associated bookings--like adding DDP)
CM is a cast member (a person who works at Disney)
There are probably more I'm not thinking of...check the stickies, or post here if you see one you can't figure out...someone will answer pretty quickly...
DVC ownership is somewhat (some would say very) complicated...it is indisputably correct that when you're spending the kind of money it takes to buy in to DVC you should know "everything"--or at least as much as possible. But truth be told, for me, I learned as I went (which may explain why I'm finding the many changes so disconcerting!)...most of it turns out to be relatively easy to manage (and figure out) once you start using your DVC...but it's hard to get a handle on all of it ahead of time.
One possible approach that might work: try planning a couple of vacations--different times of year, different resorts, different size villas. Imagine when you call to book you're more than 7 months from your check-in date, and also imagine you're 7 months or less from your planned date of arrival. Then imagine that one or more nights that you want isn't available at the resort you want, or in the size villa you want. That will help you identify what you do and do not know about what to buy and how to use your points.
After that, imagine a year when you want to go to a resort or in a villa size that takes more points than you have--and then imagine a year when you won't go at all. That will help you figure out current year points, banking and borrowing.
Good luck!
