I started writing specific help sheets based on questions I get asked - it is a bit easier than writing a full guide or manual.

Re catalyst location - doesnt matter where it is.
But it makes life easier if you put the application in it's own folder - then all the prefs files get saved in one place. This makes it easy to backup or archive a show since all the settings are in one folder.

I create a folder called catalyst, then in to that, put a sub folder for the show containing the catalyst application. This makes it very easy to duplicate the show folder for backup - always working from the original folder and all the copies become the backups. This means you can always reach the current version from task bar shortcut.
A lot of people leave a folder on the desktop, as it's easier to find...
