WTF is my.evilmilk.com ? It is evilmilk's "sister site" where users control the content. You don't need an account to view the pictures, but you can create an account here. With an accont you can submit content, and get some extra perks on the site, including double upvote points and the ability to see all posts, even ones tagged as NSFW. Your newly created account will allow you to comment on both sites.
Registered Users can click on the upload meme button just above this section. From there you can add captions and drawings to markup photos. When you save the photo, they will stay listed under your account on my.evilmilk.com and they will also show up here. Registering for an account is free and easy, can be done here.
