I'm not really sure what happened with all of that (for the SO project) either and you're right, it does seem rather strange that it wasn't used. From what you can tell (without giving it all away because I haven't received mine yet and would like to have a bit of a surprise

), but from your package, does it appear as if anything was used from the fans? -- Just wondering if only some things were chosen and not others? Also, is there anything written about it in credits, etc.?
For R.I.S.E. -- I can understand your frustration also and I think it's true of the current RW team -- I imagine that a few years ago (when Tina left) that during those changes that were made, they had decided that there would no longer be one person devoted to PG fans, correspondence, receiver of gifts, quiz maker, etc. -- I, also, really miss those days and the contact that we seemed to have with PG.
At the time that Tina left, I think a decision was made that it would be a good time to have a person take over the handling of correspondence (Rachael), but that it would no longer be the sole job of someone to respond personally to each and ever piece of mail (regular and/or e-mail) -- which is how it had always been from the beginning. It's understandable that one person cannot handle all the correspondence that PG must get these days (sorta makes me long for the old days when he had just a cult following

).
During that time (a few years ago), RW was going through some changes and that's when they listed the "Important Information" (under the FAQs section -- listed below here under Details about us). In the meantime, I think they (RW) try to do what they can to keep in contact with fans, but as you've noted, it's just not the same.
I wish that we still had the quiz and/or contests from time to time, I wish there was another Tina-type person (or better yet, Tina, herself!

). This is not to criticize Rachael, who I'm sure does a great job.
As for gift-giving and wondering what happens to them -- I honestly have never given it any thought. I still will periodically send a gift when the spirit moves me, but honestly, I have never really sent gifts to PG, himself (other than a special birthday gift which a few of us lunatics went in on). My gifts have always been to the people with whom I've had contact -- Penny, Tina, etc., -- and they're usually edible -- chocolates


, so if they don't use them, it's their loss

(and of course, if they choose to eat them, it's their "gain"

).
Kind regards to all
