One of the key things we found from the first year was being able to cut down the cost of support.
Although both @ronperkins and myself had a long history in Software and Support we both had limited time to support the product and push forward other projects.
So we decided to add in deeper system logging so if a customer had a problem, instead of us spending time talking to them and trying to find out what they had done, we could now track their journey automatically through the logs and see what had happened.
This started to reduce our support time down to a fraction of what it was. Nice Result!
