Based on the interest so far, I have created the wiki page - Community Contributions · frappe/erpnext Wiki · GitHub for current list of module leads. Feel free to update in case of errors.
As few people have already mentioned, it would be good to have something better than google spreadsheet to manage this. Ideally I would love to use erpnext.org for managing all the module activities. Perhaps erpnext.org module owner @kolate_sambhaji could spend some time looking at that. The details are better discussed in erpnext.org community call/module wiki page. Till then, I would suggest each module owner to
- create a small wiki page with your team members and link that page from ‘Community-Contributions’ page.
- Start the tagging/answering/organizing calls exercise
As we make some progress with this, certainly we need to measure the improvements this initiative has brought. Till we have a better mechanism in place, the activity in module page should serve as a measure of effectiveness of this exercise.
