In my studio there is a lot of stuff going on that I want to keep track on. So I have started setting up a personal wiki (running localy on a netbook) to keep track of everything. I'm in the process of adding pages for everything and anything I can think of so far. I'm making pages for plugins, tracking and mixing techniques and I'm going to set up dedicated pages for each project I'm working on.
The great thing is that I can link pages with additional information (projects to used plugins, plugins to specific techniques, etc.). Also the wiki is also a document and files-management system; for example I upload the plugin-file, it's PDF-manual, related skins and soundbanks al onto the page for that plugin. I also have every related link for that plugin on the page like it's homepage, the related KVR-page, any specific forum discussions, etc. The wiki also let me drag in specific news-feeds (for a plugin I use the KVR-feed for that item) so I can see in my wiki when a new version is released. Besides all the linked stuff I have notes on installation, any quirks and possible workarounds, howtos, etc.
Using specific plugins (for dokuwiki) the wiki builds links between pages. So if I mention a certain vst-plugin on another page (like a tracking project page) then it is automagically linked.
Maybe some people here like to do the same, I'm happy to help
The wiki I use is DokuWiki, very simple to set up. You need a webserver running on the machine where you want to host the wiki. It's no problem to do this on a DAW as it uses close to no CPU at all but you can set it up on another computer (like I did) and connect to it from your DAW (if it is networked).
Download DokuWiki:
www.dokuwiki.org
Webserver (if you need one):
www.xampp.org (get the xampp-lite version, installation is explained on the site as well).
First get xampp up and running, just follow their instructions and you should be fine. Then copy the dokuwiki files to the htdocs directory under xampp (see instructions on the dokuwiki site). Dokuwiki doesn't need a database so getting it to run is very simple.
