When you say they expire in February I'm assuming you mean it's a February Use Year which means the points must be used by Jan 31st, 2006.
Keep in mind that no matter how you do it, there's going to be a certain amount of trust involved.
If your intent is to transfer your points to someone else's account, and have them transfer points into your account, then the two transfers will have to be done about a year apart. For any account, you may transfer points in, or you may transfer points out, but you cannot do both within the same year.
You could use your points and make a
DVC reservation in someone else's name, and then next year they could make a reservation using their points, in your name. Again, you'd have to make your reservation first, and trust that they would make theirs, for you.
You could make a reservation in their name, and have them transfer their points to you (This will work because there's only one transfer taking place) They could transfer 2005 points which you can bank into 2006 once you receive them, or they could transfer 2006 points. The two of you would have to work out the details. Of course this takes trust on their part since you would still have full control over the reservation you made, even after they transfer their points to you.
Just a couple of ideas.
