Hi Shishir and Santu,
Doing a meetup wherein people can contribute to open source projects is definitely a good idea. Thanks for your thoughts on this. I did have a discussion about this with Prakash Murthy at the May 2016 BRUG meetup since he's been a part of a similar event in Bangalore in the past and he did mention that these things need to be well planned.
I think it's a good idea to get a better understanding of what kinda open source projects people want to contribute to, and then I think we would be in a better position to plan this meetup. I also think it's a good idea to know how many people we could expect for this meetup so that we have enough volunteers to assist other meetup attendees. We'd also need a host for this meetup. Lastly, as Santu rightly mentioned, this would need to be more on the lines of a full day event.
I think there are certain factors one keeps in mind before going about creating the meetup page and I believe they need to be accounted for. I think having more people who'd want to volunteer in co-organizing BRUG meetups is something that is welcomed. Please feel free to contact Swanand to add you as a co-organizer on meetup.com, if you're interested. This would help especially at times when other co-organizers aren't able to make it for an upcoming meetup.
Shishir, due to certain work and travel related reasons I wouldn't be able to make it for the full day meetup in August and September in case we plan to have one then.
