If you're a new member and not familiar with Trading Places, basically it was an exchange of fic in return for art and vice versa: an author would write a story based on an artist's piece of work, and the artist would make a drawing/painting based on one of the author's stories. Snapedom is not ship-centric, so any Snape pairing will be allowed, and participants will be asked to specify which pairings/genres they are willing to write/draw, and the Snapedom mod will pair authors and artists together based on their preferences.
One difference with Summer Fest is that if both participants are willing, the artist may choose to create some sort of craft project instead of a drawing/painting--sew a Snape plushie doll, for example. Or maybe create a scene from the story with Snape Legos or action figures. If two people agree on a crafts exchange of a physical item, they will have to work out the shipping details with each other.
Digital art/manipulations are also being allowed as an art alternative. For example: icons, banners, or mood themes. Participants will be asked to state their preferences as to what kind of gift they would like to receive/give.
Sign-ups will run from May 10 to May 25; assignments will be given out the following week, and people can post their fic/art from June 1 through Aug. 31. You can sign up here, but please read therules and FAQ first. We are trying to generate interest from outside the community, so even if you're not a Snapedom member, you're welcome to sign up.
On a purely selfish note, it sure would be nice to get some Snupin artists to sign up, which is why I asked for permission to post this here! ^_^ (Snupin writers are welcome, too, of course!) Judging by the weekly fic recs on the community, Snape/Hermione seems to be the most popular pairing among the Snapedom members, although there are some Snupin and Snarry shippers, and I know there are at least a few Snape/Lily and Snape/Sirius shippers.
Personally, I have nothing against any of the other ships, but I don't think that I'd be able to write Snape/Hermione or Snape/Harry convincingly. However, depending on how many people sign up, there may not be any Snupin art available, so I've offered to write gen or Snape/Sirius as a 2nd choice. And it seems to be a rarepair, but I've come to love bluestocking79's Snape/Luna drabbles, so I've listed that as a possibility as well, along with Snape/Regulus. But I do feel most comfortable writing Snupin, so I'm hoping I'll get the opportunity to pair my two favorite wizards up together yet again! So come on, you Snupin shippers, and sign up for Summer Fest! ^_^
