@iamnarendrasingh You have so many wonderful ideas! And thanks to everyone who has expressed interest in the concept.
I really like @A.N.M_AL-IMRAN's idea of coming up with a plan. You could start a wiki topic for example and encourage people to add what concepts they'd like covered. And I think there's a great exchange concept here as @A.N.M_AL-IMRAN said -- maybe PersonA wants to learn about TopicA and knows about TopicB and PersonB wants to learn about TopicB and knows about TopicA. Perfect sharing opportunity!
There have been so many fantastic community ideas shared recently like this one or the Newsletter for ODK concept and I wish I had more time to engage with all of them! My high level recommendation would be to pick one of these first and start experimenting with content and processes that can be evolved over time. It's hard to start many initiatives at the same time! I think some newsletter / documentation writing would be a good place to start because that could help structure a future course.
As for my personal involvement in these initiatives, currently I feel responsibility to focus on software development as much as I can because there is so much to do! I'm happy to offer feedback and can certainly contribute but I won't be able to lead these kinds of efforts at the moment. I encourage one of you to!
