Internet registration

[John Boyd;CRENP]

This message is not Unix-specific, but I was at a loss as to where it
SHOULD go; so replies direct to me would be more appropriate.

My question: How, and as important, WHY does someone register his
individual PC into the .org or .uucp domain as opposed to .us.  What
information must be known, what questions need to be asked/answered in
order for the individual to make an intelligent decision as to which avenue
to persue.  I made an inquiry to postmaster at uunet.uu.net, with the
following question: How do I go about registering my home PC into a domain
where I might receive news and a certain quantity of mail?  What I received
was a form to *register a domain*.  Not exactly where I was headed.  At the
top of that form was a small blurb that said something like 'Individuals
may want to contact westine at isu.edu to register'.  Well, I received an
application to register in the .us domain.  Within *that* form, it
references the fact that one doesn't want to be registered in .us and .org
or .uucp @the same time.  That makes sense.  Trouble is, I cant't seem to
find the info that I need to be able to decide for myself whether I should
be persuing .org, .us, or .uucp registration.  I am currently making
arrangements to get the necessary software and 'feed' connections from
someone who is currently getting a feed from a local university.  If there
are any bases I haven't covered, I'd appreciate someone filling me in.
Your time and assistance will be appreciated!
