Agreed, I think mostly this is because of that all leaders and developers of this project have a very correct attitude and the same goals. Every time there's a reason to flame or accuse someone/something it is immediately interrupted. Its not only a stable but a clean community, no code-stealing, no dishonesty, no bad relationships with others. Ultimate goal is to learn and this is one of few projects of this size I've ever seen that actually has managed to accomplish this. I'm actually amazed by mangos, watching sooo many other projects failing after only a few months or a year. Mangos is the only one still standing and despite that still having a very bright future.
This have inspired me to start my own open-source projects and has taught me most of the things I need to know about how to run a good and healthy open-source community.
Cheers & Thank You MANGOS
