What is more, the support is excellent. I had a problem with upgrade process, and through an exchange of 6-7 e-mails with Markus, step by step, i got my issue solved.
Please keep up the good work!
it still can be downloaded for free as beer (previous version). Our model is similar to other open source businesses where the previous version is for as beer while the current one should cover the costs.
In return people get better quality extensions and there is no danger a project will be abandoned (what you often have in non-commercial opensource projects).
Thanks for the review!
