Sorry for the inconvenience. Known Navigation header breakage, its being "rebuilt," forward and back nav should function where present.
There may be other unforeseen breakage primarily in the handbook portion of the wiki.
The Table Of Contents section of each "PC-BSD® Users Handbook" page may be the best workaround.
I used FreeBSD (2.2.6) for a short while long ago, and now have returned but to the PC-BSD (8.0) version. Once upon a time I managed to get X windows running in BeOS, and in the olden days I had Gno/Me on my Apple IIgs. When I was in school, I took classes in BASIC, LOGO, Pascal, and C. Most of my programming was for class assignments.. and although I was highly interested in writing my own software, I got sidetracked with playing computer games. These days I am regaining my turbo-c-shell skills, my building/porting, troubleshooting and system administration abilities, and trying to be of some service to the PC-BSD community. You may have read my blog A Little Demon on My Desktop at the PC-BSD advocacy site. --Tigersharke 18:43, 19 December 2010 (PST)
