If you open the clan chat there's a button on the lower left to open extended options. Click it while keeping your cursor over it. Then click on the cork board looking button. That will tell you who has an avatar. Then I would suggest asking that person in clan chat.
on dxp weekend i aim to have the avatar out as much as possible. i will most likeley be off-world using portables however. or else i will be using portables on our clan home world w44
