It is bits and pieces swipped from the wp support forms, and a we changed the colors.
This install, was in import from punbb. I did not make an import script or anything automated. I did it all by editing the sql files. The bbPress version went live about two weeks ago.
I have a second a second install, that I did alot of work on the templates, made it all table free.
I am not yet ready to share that one, but since this forum is up, and all the recent work here at bbPress, I am cleaning it up and re-installing it. Once I have it a little cleaner I will share it to.
