:new: Assignments are (finally) sent out! Please look them over and let me know if there are any problems! :heart:

So, as the title says, we're hosting another Underswap Secret Santa event! This one will be themed around the Day of Love, Valentine's Day!

:star: Here's the lowdown :star:
Each person will be randomly assigned someone to draw for. In turn, that person will be assigned somebody else... so on and so forth. And everyone will receive beautiful artwork! Sound fun? Artists are loosely categorized by skill level for this event. Please put forth your best effort in making your gift!

:star: How to sign up :star:
:bulletred: You have to be a member of UnderswapAU! However, joining just to participate is fine~
:bulletred: Comment below with three things you would want your partner to draw. No more, no less.
:bulletred: Your wishes must be Valentine's Day themed! This could be your favorite couple romancing each other; a parent celebrating with their child; or a solo Monster kicking it for Single's Awareness!
:bulletred: That's all! You'll be added to the list here, and your comment will be linked here as well.

:star: Timeline :star:
:bulletred: Signups are now closed!
:bulletred: Assignments are now handed out!
:bulletred: Gifts will be due May 1st, giving you one month to finish yours!

:star: Artwork guidelines :star:
:bulletred: This event is Valentine's Day themed! Your requests and fills must be at least tangentially related to the holiday!
:bulletred: However, group rules still apply, so for this event, OCs are not allowed, sorry. Your wishlist also has to be Underswap; that's what makes it an Underswap Secret Santa! Combination AUs or Swap AUs such as Swapfell or Storyshift are allowed, but canon and other AUs are not allowed!
:bulletred: All visual mediums will be allowed-- pixel art, digital art, comics, traditional art, etc.
:bulletred: However, for this event, the following will not be allowed: fanfiction, MMD/pre-made 3D models, bases, or traces of any kind.
:bulletred: Please make sure your art is complete, and, if traditional, scanned well; no sketches, no poor photographs of traditional drawings, etc.
:bulletred: I know that seems like a lot, but here's the most important rule: Have fun!

Something tells me that there is a huge backup with submissions... which could be a problem if people are trying to do Secret Santa. Is there anyone that can do Submission Approvals soon? If it's a family matter again, then I totally understand ^^
Echoheartx Featured By Owner 2 days ago  Hobbyist Digital Artist
This seems to be happening frequently lately. I hope they're doing alright but I think perhaps they should consider getting a co-founder or contributor to help sort through things in the group/accept or reject submissions. I know I'm waiting on three to go through right now so I can only imagine just how many there are all in all.
Cyane-ei Featured By Owner Mar 30, 2017  Hobbyist Digital Artist
well leaving the group :/ nothing gets accepted AU crossovers with underswap get all rejected too
DrGaster Featured By Owner Mar 31, 2017  Hobbyist Digital Artist
Sorry to hear! I get so many misplaced submissions, it's impossible to have the time to correct all of them. In the future, if you decide to submit again, try just submitting to the Unsure folder.
Cyane-ei Featured By Owner Mar 31, 2017  Hobbyist Digital Artist
i put all in crossovers since it was mixed :/ waited over 1 month for any decision to have all declined without reason.. i just left :/

Should shipping Canon X OC count in the Ships folder?
