*cracks fingers* OHKAY! wells i think first you have to become a member of a group (maybe) but if not then ignore these steps But go to the top right hand corner and press watch/become a member and then you might have to wait for the founders to accept your request. After you are a mamber, go the the top left of the page where it says your name and click on it. A little box should come up that gives you options such as contribute deviation, suggest a favorite, and leave the group. Press contribute deviation and you can prolly go from there! ^^ And to make little icons you kinda have to memorize the names of them, but say if you wanted to put a picture of the me gusta meme then you would type this:
:icon megusta plz:
except without any spaces. Without the space you get most icons will be like this and it depends on the icon wether its a gif or not :> so like i know :icon epicclap plz: is a gif -> and if you see one you like than hover your cursor over it and it will tell you the name of it and then you'll just type :icon (nameoficon) plz: and it will come up!
