I did. The majority of my avatars on here will most likely be drawn. On other forums that were more geared toward, fiction and roleplay, I've used real women who I admire and/or were similar in appearance to my mental image of myself. Those avatars fit the fantasy nature of those forums.
Here is more about reality. About all of us coming together to share our journeys as figure out, and become who we really are, as well as providing support for each other through our real, everyday issues. Doesn't seem right to use a real person here that wasn't me. And as I'm not yet comfortable enough to use myself as my avatar, I'm sticking to my sketches and such.
I think the kid in Calder's avatar is adorable.
