What is an "agent"?

One of the two factors on which our pricing is based is the number of agents. 

A survey can be associated with a particular agent (e.g. Asking how a specific customer support agent performed), but also with things and actions you'd like to get feedback on. An example of this would be collecting feedback on a weekly newsletter, or on your shopping experience. Each plan allows you to collect feedback for a combined number of agents, things, and actions. If you exceed the number for your plan, your plan will be upgraded automatically starting next month.
