Welcome to the new users... When the site was launched there were quite a few people that signed up and some good initial feedback which I implemented. Since then however, registrations have slowed significantly and there has been no feedback in a year. As a result there has not been any updates and I never got started on the community aspects of the site.
From analyzing the traffic, it appears people are having trouble understanding the workflow of creating a customer, then a car, then adding a detail each time that customer returns. I have played around with a few ideas for streamlining this process, but none that have made it into production yet.
It will stay online in its current form and will always remain free to use. There are some users with hundreds of records in the system, but a most people have only entered a few (or none at all) and have not returned in quite some time. I welcome any feedback from new users and any one who is still using it, and if there is still demand then I will continue development on it.
