MyBB has always supported animated avatars. Or rather, it’s never not supported it, because there’s no special implementation required to support them.

Exactly as Equinox said. I've been using a gif on mine for probably about 7-8 years. I suppose the same is actually true of our userbars - I totally forgot the Agency one had movement until I looked at your profile, Equinox xD

Nice avatar though @shakes . It's not too gaudy/harsh on the eyes like some can be. It strikes a nice enough balance with SL too.
