Max,
we replied on both of your emails. It’s rather strange that you didn't receive them.
As for your question, you should purchase only 2 licenses for your admins.
By the way, let me explain what's wrong with our phones. Actually nothing wrong with them, they are working.
But the thing is that SmartCode is a Singapore based company and the phone number 650-472-2345 is just a call forwarding service, which transfers all calls to our Singapore number listed on the site too. This way when a customer phones us, he doesn’t have to pay international calling rates, we do it for him. The only problem is that Singapore is on very different time-zone from U.S. and probably when you called, it was late night here.
