Welcome to the Achaea Forums! Please be sure to read the Forum Rules
If you've lost your vanilicon or avatar in the server moves/shuffles and have a blank avatar, you have a couple of options here:
1) Set your avatar in Nexus, it will translate over to the forums on your next login/logout.
2) Add a picture here on the forums and delete it, which will restore you vanilicon if that's your preference.
