adding to what Applebloom said, you must make 5 posts and they must be outside of the Welcoming Plaza and Cloudsdale Coliseum

i already posted five post, so where do i go

All your stats say 0 posts...that's strange. Once you reach 5 outside of the Welcoming Plaza and Cloudsdale Coliseum you should be allowed to upload an avatar from your settings.
