@julian To my unaided eye, the logo we have now and one you linked look the same.
Designers, right? I am told there are a number of small changes, but they very much looked the same to me.
The inside of the B has a different shape, slightly reminiscent of a speech bubble. Also the gradient, and we finally have high quality originals to work off of (we lost the original SVGs)
Edit: Oh, and yes, I mean the logo on the forum
