403 Registration not Authorized =)

[Simon Iremonger (wiltslug)]

Dear All,

I was experimenting with XMPP/Jabber messaging, and I am finding
  that I am not allowed to register on jabber.earth.li --
  403 Forbidden =).  Maybe registrations are locked down by
  IP-address ?

May I be allowed to inhabit the earth, or at least the jabber
  server, despite having defected to the other place ?

With many thanks in advance,

--Simon
