The Wiki

Welcome to the documentation Wiki! A Wiki is always a "work-in-progress" and this one is no exception.
This Wiki is created and maintained by the user community (that's you and me) so - please - approach it that way.

If you find the answers you're looking for - brilliant. But if you don't... Don't forget that no one's paid to maintain this - so go find out the answer, experiment, ask in the forum at and then add the Wiki entry yourself :) You get a lot of benefit from understanding something well enough to document it. Careful though, it's addictive.

Please visit the Contributors portal for editing, help, housekeeping, discussions and more.
