as a new subscriber, a wiki would be very helpful.

I find MediaWiki and DokuWiki to be very good.

There's also a DocsWiki but I know nothing about it.

I think that tutorials are very good, and they are a good data base when you need to use them for anything in the work. More or less tutorials are al the time, a good way to move along into anything that;s new for you..i used to do photoshop tutorials, and not all the time i was able to use the photoshop at its capcacity. Well the tutorials were very good then to know how...
