We are currently in an age where a large portion of open source apps are actively maintained, users understand more about open source than ever before and open source software is almost as good, if not better, than their proprietary counterparts.
This is just a huge thank you to anyone and everyone involved in the making and maintaining of open source software.
As a regular tester, I do my best to provide any feedback I can to make your vision come to fruition.
Often the most difficult part of solving it is being able to reproduce it / find the exact situation in which the problem occurs.
