I set up a Wiki system for keeping track of little tricks and tips in the shop. I put it on the same server that runs some scripts for ShatteredWindows.com. Makes it easier to find fixes to common problems than using Google, and we can note fixes to the really wacky stuff.

I have found that it is really simple to set up. Unpack an archive, upload some files, change a few permissions, hit a URL, and voila: installed.

Of course, the Wiki software itself is insanely easy to use, but difficult to master.
