Whenever I try to do a new sig I get “BB code url is not allowed”.

P.S. An Gadai, care to send in a photo for the gallery?
Good god no, I don’t wanna break it.
I’m pretty sure only members can show sigs, so that might be the problem.
Is that a recent rule?
I don’t know the timeline, I just went and looked at the rules thread.
ETA: Hm. Or an old one? Not sure!
I’m pretty sure I was using ego sigs even before I was sponsored…
Yes, a fairly recent change but one that has been in place for a while now.
Do you mean only members can put URLs in their sigs?
Aren’t “fairly recent” and “been in place for a while now” opposites? 
Sneak-bragging!
Yes but there’s a point of equilibrium, an instant in time when something fairly recent transitions to something that’s been in place for a while now. At the midpoint of that transition, it’s both, like Schrodinger’s Cat.
Against considerable odds, TubaDiva happened to post at that instant in time.
No, as of a couple months ago (not researching that) only paid members can have automatic sigs.
