I joined in Sept. and also have a Dec. use year. I received the $86/point at SS and already made my first reservation. I was told that I do not receive the 2005 points. So when booking my July 2007 res. I used all of my 2006 points (that won't come until Dec 1) and borrowed from my Dec 2007 points.
So, on the website, there are two areas I can look to see what my points activity is. One site has me using 2005 points (which I shouldn't have) and borrowing from my 2006 points. The other page (where my reservation is confirmed) has me useing my 2006 points, and borrowing from my 2007 points (as I believe it should be and was told over the phone when I made the res).
Anyway, all that to let you know that I think if you took the special deal on purchase points (either $91 or $86 per point) it negates the idea of getting 2005 points. The points page must not reflect this and therefore credits us for having 2005 points when we don't.
OH BUT THE JOY IF WE REALLY DO!!! But I don't think that is the case.
