I am giving one of my Obi units to my daughter. Since my units are associated with my acct, they all share my speed dial. I want my daughter to be able to have her own speed dial and it appears the only way to do this is with a separate account. I see how to remove this unit[100] from my acct but do not see how to establish a new one. I do not remember what I originally did to start mine or set mine up.
