On certain profiles, avatar flair is shown. By this, I mean the founding members or moderator descriptors added to a profile.
I think that it would be helpful if game makers in the various craftalongs could have some flair added to let others know who they are. Then participants know immediately who they can go to with questions. It may also be a way to get new participants to join in the craftalongs when posting within the community.
For now, I think you can accomplish what you want by editing your profile name to the flair you want. I just tried it on my account and it will take a good number of letters. So instead of just āJamie Storerā you could change your name to āNerd Games Captain - Jamie Storerā and it will show up by your avatar.
