Right, you must use the short hash (as DNS limits individual name
segments to 63 characters, GNS uses the short hash). Where did you read
that you should use the long version?

That's a reasonable suggestion, I'll put it on my looong list ;-).

Just 'myzonename', as 'fcfs.gnunet' is always going to be used.

Either command will generate the same kind of key in the file, just the
hash function used to generate the textual output will be different.

If you install and configure GNS correctly, then your name will show up
when you lookup 'yourname.fcfs.gnunet' using DNS (assuming you've put
some "A" or "AAAA" records under the name "+" in your zone using, say,
'gnunet-setup'. I don't know why 'fcfs.gnunet' doesn't show up in your
version; however, we have fixed many, many bugs since 0.9.3 including a
few with respect to GNS and the GUI, so you might want to use SVN HEAD
or the (soon to be released) 0.9.4 to see if that helps (sorry, but you
are using bleeding-edge features).

FCFS allows you to create a 'PKEY' record in the fcfs zone under an
(available) name of your choice. All requests to that subdomain will
then be delegated to your zone. If that is not a sufficient answer, I
suspect the issue is that GNS itself isn't fully clear to you, which is
understandable as we're still in the process of documenting it. If you
have any specific questions, please send them to us and we'll try to
improve the documentation.

This particular FCFS implementation limits registration to one name per
key to encourage users to be reasonable --- otherwise we might have some
"funny guy" registering all names with up to 8 characters just for fun.
However, other FCFS zones can have different policies and in your own
zone you can obviously do whatever you like to do.
I hope this helps!
