It is semi-actively maintained! There are parts that I maintain and other parts that volunteers do. Presently we could use someone to maintain the library as Handy Andy has done for several years (thanks to him!).
I know of some sections that need work but a reminder will help.
As a matter of fact, there are several articles that need work on. Some of the articles had external links and the author disappeared and the links did too. Who would like to volunteer to work on the whole section? I will provide some assistance to get you started. Hopefully you have some good editorial skills! You also get to be a member of the exclusive, behind the scenes area called "The Board Room".
