You just might have noticed that my little picture of Yoda is a tad less little today. I found a neat code on Proboards Support that lets me change the limit to the size of avatars, or even remove it completely.
Well, I didn't do that, but I did up the size to a maximum of 150 x 150. The same as GBCentral, by the way. As before, if your avatar's "natural" state is larger than that, the board software resizes it automatically.
I installed the same hack on the GBWC and Omnibus boards, so you can enjoy that same feature there too.
