More information can be found on the offical blog.
The event is organized by four moderators: Kat, Lara, Ellie, and Edessa. Though all are active across all sites, they specialize in FanFiction, Wattpad, Tumblr, and deviantART, respectively.
Responses to the prompts are posted on Tumblr, deviantART, and FanFiction.net. They are tagged or labeled with "SG10thAnniverse" as well as the weekly theme tag, which allows the moderators to find all the entries. The mods then share or reblog entries to the SG10thAnniverse blog which acts as a hub and collection center for the entire event.
Some entries are also submitted straight to the blog via Tumblr's submissions box.
The structure of the event is as follows: There are four weeks (planned so far), each associated with a different theme or prompt. These weeks were scheduled to fall evenly around August 1st, the 10th anniversary of the series. The themes are scheduled thusly:
Week 1: 7/20 - 7/25
- Theme: Selfie Week
- Tag: #SGSelfieWeek
Week 2: 7/26 -8/1
- Theme: Non-Romantic Pairings
- Tag: #SGNoRomoWeek
Week 3: 8/2 - 8/8
- Theme: Alternate Universe Week
- Tag: #SGAUWeek
Week 4: 8/9 - 8/15
- Theme: Romantic Pairings
- Tag: #SGShipWeek
Late entries are allowed for any of the prompts.
Due to the uncertain nature of the 10th anniversary of the series--specifically, little to no news about the books being released--the schedule is open to changing and expanding as the moderators get more information.
