DNS server setup

[Matthew Freeland]

Hi.  I own the domain mfreeland.net, which I wish to use as my personal domain 
for email/web site/ftp/telnet/etc.  I read a HOWTO for BIND9 and set up the 
server.  All seems to be working when I dig to localhost, so I think I have 
everything configured.  If you need it, I can send coppies of my named.conf 
and zone files.  The problem I have is that when I went to my registrar, 
godaddy.com, and tried to change my nameservers to ns.mfreeland.net (my 
machine), it said a) you need 2 nameservers, and b) the nameserver is not 
registered.  What must I do to get the nameserver registered, and is there 
any way to get around needing 2 nameservers?  My server will be running from 
my dorm room, so I don't think they'll want me running 2 PCs fulltime.  I 
understand that the slave server is supposed to be there in case the primary 
fails, but honestly, I don't care if my website goes down for a short time; 
it's just a private website.  Thanks in advance for any help.

PS   Sorry if this goes out twice, I'm having trouble with the emtp server 
that my address is currently routed to.
