Wow, what a great thread. I'm new to swapping, but I too have been thinking of ideas since I saw the concept LOL.
To start with the non-Disney stuff, I am *VERY* interested in the pet swap. I only do Disney scrapping, but I realized I had a ton of cat pics that I am doing nothing with and really would have fun with that. I'd like to request, though, that you divide it up into dog and cat, LOL. I don't need doggie parts...and I'm sure others don't need my kitty parts.
As for Disney - I'd definately be up for New England E's park swaps. That sounds like so much fun - I'm all about park-specific scrapping. I think MK would be a great place to start.
I also really, really like the idea of the World Showcase swap. I'm planning a WS layout right now for the pics I'm going to take on my next trip, and had planned on doing it as soon as I got back but I'd wait for a swap if that was going on. It might also be fun to do a paper trade with that one as well - there are some great country papers out there (flags and such), but it's hard to find them all in local stores. I was actually going to order a bunch over the internet. Would be more fun (and a lot cheaper) if people got multiples of what they have available locally and traded those for sets as well.
I like the idea of shorter swaps as well. I don't have the longest attention span, and many months for one swap doesn't sound as much fun. I'm a newbie, though, so what do I know.
I also like the idea of trading store-bought stuff as well...I've become quite a good scrap shopper (mainly thanks to the help from people on the scrap forum!) and would have fun getting deals and stuff on those.
In the spring, after I've participated in a few, I would like to host a simple one. I'm a big eBayer, so I go to the post office more days than I don't and am a GREAT mailer, if I say so myself LOL. I'd really like to do maybe a Tower of Terror/Haunted Mansion swap, or possibly a Living Seas/Nemo one (since many people will be experiencing that attraction for the first time). If I hosted an attraction swap like that, one of my contributions could be some actual in-ride photos that people could add to their own, if that interested anyone (I take lots of inside-attraction pics).
Sounds like so much fun...I can't wait to try!
