A lot of that information is there. I'm just very conscious of the need
to make everything read well - too much documentation feels like it's
been thrown together, and is a horrible read.

One piece of documentation is a perfect example of how readers can miss
stuff because it's too obvious ... :-) I had trouble finding out how to
do some operation to do with text entry in a word processor. I couldn't
find any reference to it in the index. I searched high and low. Then
somebody pointed it out to me in the manual - it was repeated on nearly
every other page!

I'm planning to condense a lot of this thread into the "scary things
that are easy to fix" page, but your idea of a checklist page sounds
very good. Expect it to appear some time "soon" :-)

(Note also that a lot of this stuff I don't have personal experience of,
so it only tends to make its way into the wiki when something crops up
on the mailing list.)

Cheers,
