"idgits"?

LMAO.

I'm stealing that. and blaming you

All those idgits complaining on the forums.

It's not region specific, per-say. You just can't sign up without a US/Canada ip address. And must register with a physical US/Canada phone (cell or landline).

Oh and must call from (and to) a US landline, cellphone OR a US VOIP #.

However international people (I did make an [outdated] guide on this) can register from a US IP (proxy or friend), register with a SIPgate VOIP # (google thinks it's a physical phone ) and then use Gizmo or other SIP client to call and receive from US #s.
