David & Adam,

don't worry.  Although I may not speak for the others on this list, I
think most people here are perfectly happy to have questions from
newbies!  The more people that use org mode, the better.

All I would say is that, besides the manual, you have good trawl
through the Worg website that has very many useful tutorials and
descriptions of different usage scenarios and workflows.  I found Worg
indispensable when getting started with org.

But please don't feel afraid to ask what might seem like silly
questions.  The worst that will happen is that you get pointed to one
of the sections in the manual...
