What is the differences between .biz and .com domains?
Pretty much nothing, .biz domains are new so there are
less names taken, and thus better choices for new ones.
Transfers _are_ different. info/biz and us domains
need a "transfer key", or "auth code" to be transfered. Basically, this
is a password that the domain owner needs to give to the new registrar
to prove they own the domain and are allowed to transfer it.
Unfortuntely with most registrars, you can not get these
"passwords" automatically... you actually have to contact the registrar
and ask for them (at least in our limited experience).
registered with us you can get this from the 'manage profile' section
of the domain management area.
More details to be added as they arise.
