Okay, here is the collection:
http://archiveofourown.org/collections/ssss_artd_100I've copied the rules and the prompt table there. That way everyone will have one easy place to find it.
I find that when adding a new work to a collection, the easiest way to do it is to go to the collection page and click "post to collection" (top right hand corner). It will auto-fill the collection field for you.
If you're adding an already-posted work to the collection, here's how to do it:
-Go to the edit page for your fic.
-Scroll down to "post to collections/challenges". It's below the field for the author notes.
-Start typing in ssss_artd_100. It should give an option to select the collection. Select it.
-Scroll to the bottom and save as normal.
This was created as a sub-collection - basically what that means is, if we decide to make other SSSS/aRTD challenges, I will easily be able to create a new collection for those, and they will all be linked through one parent collection.
Please let me know if anything needs to be added or changed.
