There is a Tumblr page out there, of the same name as this group, which gave birth* to a lovely pony mare, named Milky Way - an Original Character based on "My Little Pony: Friendship is Magic" show.
(Note that as of Dec 2018 the tumblr is no longer updated, however it remains as an archive. The tumblr comic can also be found on derpibooru and the artist is on twitter @FlashEquestria)
She lives in the city of Trottingham, located in Equestria, and her job is delivering sweet, delicious milk to any thirsty pony who needs her services. She's a beautiful mare with a cream coat and a mane of soothing blue, and she has a very special trait... one I'm sure you will quickly figure out.
This group concentrates on collecting art featuring her. There's little of it on DeviantArt right now... so why won't you help us a little and contribute some Milky Way fanart to our group?
*Or, at least, brought her to light.
All membership requests are automatically accepted. You don't need to be a member to submit art, though.
First, remain respectful to all members; no bashing, insulting etc., always remain nice. Or, well, at least try to. Please?
Second, we accept only art featuring Milky Way. It doesn't matter if there are other ponies on the image or if she isn't the main focus, just as long as she is present there.
Third, any kind of art, mature or not, is welcome, with exceptions. Gore and violence will not be accepted, as this is a sexy fan club, not a violent one. Also, any adult art featuring abuse or rape will not be tolerated.
Fourth, always submit your deviations to the right folders, as detailed below:
There are two types of folders: "Safe" and "Mature". The first one should be pretty much straightforward; the second one is for anything that requires adding a Mature Content Warning. Each of those two types has two folders: "Milky Way alone" and "Milky Way, group". As you can imagine, the first ones are for deviations with just Milky Way, and the second are for anything that features her among other characters.
"Vector Resources" folder is specifically for any vectors that are meant to be resources for use in t-shirts, wallpapers and various projects. If you don't know what a vector is, it's suggested to take a look on Wikipedia or on the MLP-VectorClub's page.
"Other" folder is for anything that does not seem to fit any other folder.
Regular members cannot upload anything to the "Featured" folder - only administrators decide what can be featured there.
You can always ask the Founder (OokamiTheWolf1) if you're uncertain where to upload the deviation or does it fit the group at all.
