Ok, here’s what I have, commented. The comments that start with “VILI” are mine.
Please keep in mind two things:
a) This is strictly speaking a WordPress plugin, not a bbPress one. The functionality is simply extended to also cover an integrated bbPress installation. (And yes, this means that you need to install this in your WordPress, not your bbPress.)
b) I hacked this for my own purposes, so it may not be pretty, and it certainly won’t be ready for use without you reading through the code. If someone is interested in working to make it functional as an “out of the box” solution, then by all means go ahead.
Finally, the original Dan’s Avatar Thingy can be found here.
