BharathPeace Hi Bharath!
I too, would like to thank you for your feedback, as @luceos did. Feedback from the community is what empowers us to continue driving forwards with our community at the forefront, and we're proud to keep it that way.
All me to address some of your concerns:
Under development. Not much premium features.
Our development status is due to the fact that we're working hard to iron out bugs, and soldier on towards stable release. We appreciate that this has taken us a while, but we're proud of where we are and truly believe that we have a fantastic team to enable us to achieve stable as quickly, and as efficiently, as possible. Our extension developers (including some from our own team!) are working on premium features, and many more will be available once our core focus of stable is reached.
Vulnerable bugs. So Penetration testers easily can exploit to your server. (if you using third party extensions)
Here at Flarum, we take security very seriously and would advise that security vulnerabilities are reported to us using the correct channels. As @Franz said, you can let us know here: https://github.com/flarum/core/security/policy Please note though that third party extensions build on top of the core, and we'd advise that you continue to run your own diligence checks against third party extensions - this should always be the case.
Third-party extensions affect your existing Database. So your website will get unrecoverable damages on your SQL and rewritable script files.
Whilst I would disagree with the "rewritable script files" part, I do agree that third party extensions (as mentioned by luceos) can be confusing. We'd be happy to hear your suggestions on this. As, like mentioned earlier, we thrive off of community feedback.
We have continue to grow the team, and have been proud to even onboard @Franz as a paid developer to increase his ability to devote time to the project. We however, continue to grow. Please remember that we are an opensource project, and would welcome any input of the collaborative approach to the project here: https://github.com/flarum/core
Minimal Guides and support.
I'm going to be honest here. I agree. We've admitted internally that our documents have been neglected somewhat, particularly with the team pushing so hard to focus on a stable release. This is something that we are working to resolve, and I know that @jordanjay29 has worked hard to bring people into the documentation team, and improve existing documentation where possible.
To assist our efforts here, it would be very helpful if we could identify what guides or documentation you feel is lacking, and how we can improve these for you.
Once again, I thank you for your continued support and constructive criticisms of Flarum, and I hope that we can continue to improve our offerings to you.
Kind regards,
Katos.
