Rui, I'd love the attached as my Avatar; except I don't know how to edit it (and remove my dulcet Essex voice)! If the first two seconds were removed then I think it would play in a smooth continuous loop.
I did ask my very "techie" brother if he could/would edit it for me (after all, he is a VT Editor with the BBC) but he always seems to overlook this particular request.
Sorry, we can't have videos as avatars, only static images. I will gladly set any picture you want as an avatar, but videos I can't. The forum code doesn't allow it.
