I would suggest using Slack, Trello, and GitHub. Make a Slack team, use their integration feature to have it post updates when your GitHub has changes made. Make a Trello team and have a board to track tasks to-do, in progress, and done for your programming team.

Then I'd suggest to expand the Slack and Trello beyond just your programmers and get everyone talking and using the same platforms. It's really powerful.

Then, you don't have to build your own platform or webpage and everyone can contribute in some way, and some can be admins, etc.
