Tips and Tricks / Troubleshooting. For example if you encounter issues while setting up devstack - any time you face an issue and solve it you could post here. Then others will be able to use it to look for solutions.
From @kshitij’s suggestion:
One forum segment I think it would be nice to have is for Tips and Tricks / Troubleshooting. I’ve encountered a couple of odd issues while setting up the devstack, and I found answers on Mattermost, but it would be nice if any time you face an issue and solve it you could post here. Then that can be the first place you look for solutions.
