To start the extraction with Novapool, you must create an account. This is a fairly simple and standard practice in most major pools. Again, it's very simple. You can easily set worker and hash alerts if a minor is abandoned or underperformed. The site also displays the expected earnings / TH / day in several places; including the pool statistics page on your dashboard.
An interesting feature available on the home page examines the profitability of most of the equipment available for the past two years. It works like a profitability calculator by allowing you to enter your utility costs and see your potential daily earnings per machine. They also offer additional functionality and monitoring such as an app, which I will be testing in the coming days.
