I love to be here. But I have no idea how not to "be a dick." Where do you all find these avatars? I'd love to know!
Welcome. To set your avatar you first have to have an image saved on your device. Could be a photo you took, a web meme you found or whatever you think represents you best. Then, on the upper right of the page, click your current avatar which is between the moon and mailbox icons. The pop up menu has “Avatar” which you click and then upload your image. Voila!
