Hrm, I'm torn on the placement of PC-BSD.
On the one hand, it's based on FreeBSD, uses pure FreeBSD underneath the GUI, and could fit under the FreeBSD heading.
On the other hand, it's quite a different beast from FreeBSD, with all the GUI goodness, and could be considered separate enough to stay under Other OSes.
Same with MidnightBSD (based on OpenBSD), pfSense (based on FreeBSD), nanoBSD/picoBSD (based on FreeBSD), and similar "distros" of the BSDs. Perhaps adding a "*BSD Expansions" or "*BSD Distros" or "OSes Based on *BSD" forum under each *BSD heading would be useful?
Or we could just leave things the way they are.
I'm flexible.
