OP I don't know if that depends on rank but all I feel about that is that, it can only happen to those members who have been here for long like those who have better reputation, those prominent members per say, don't really know how to place them but you know what I'm trying to say.
Live animation or sig as you call it is some how hard to see on members like you and I. Don't take it to heart 😅 but you have to work your way through to that stage.
But why do you want to have such? Because to me it seems you feel like having it, I'm I correct?🤔
Well, it's not because of their reputation or how long they've been around the forum. Turns out, the rule against animated avatars was introduced later, and those who are still rocking those quirky avatars probably never got around to changing them since then. I stumbled upon this after reading a few posts.
Now, when it comes to animated signatures, Jayce mentioned that they aren't doable with BBcode, and HTML banners are Banned. So, if we want to sport cool avatars and signatures like that, it looks like we'll have to wait for Thymos to make an announcement.
