We still need to agree on the Service Levels. Chris made a great start in the wiki, which I adjusted to make it somewhat more in line with the ColloCall prices. But I read doubts at your part, let me cite from the Systems architecture thread:
Now, I think people will want to know what they get before making any level of contribution. If we tell them “you need to pay between 20 and 200 a month, depending on to be defined and implemented usage statistics” they walk away. In fact, many are asking for such definition.
Also the ColloCall prices and service level definitions are rather ok, isn’t it?
