It would be nice if upon induction into
a cabal the individual were directed to
type trustcabal. There are a lot of things
like this that would help newbies out
tremendously. Maybe implement them only for
those that check the "new to cf" box, though
I know some that are not particularly new to
cf that could use it as well.

I added 'TRUSTCABAL' to the 'See Also' list on help INDUCTION, which is the helpfile that you get prompted to check when you get inducted into a Cabal. Thanks for pointing this out!

But I kind of think this thing falls squarely on your cabal mates showing you around the cabal, explaining the cabal powers, how cabal items work, that kind of thing.
