Update here from a new user on 2.0 (2 years later). Team experience is currently still confusing and unintuitive. The same issue reported here and elsewhere still seem to exist.
From what I can see, someone has the idea that the teams view should filter all users of my github organization which are not following projects. Perhaps there’s a clever reason for this, but I currently am unable to divine it. I don’t particularly care if my users on my team are “following” a project, but if it is important to the platform, I would prefer to see all my users with a simple column that tells me how many projects they are following instead of hiding them from me. The same is true for users who have not joined circleci yet. Just give me a column on my user list with a checkbox or something.
Priority 1, provide an easy to get to list all the users sync’d from Github, and show whatever statuses are relevant to CircleCI in that list. This is what the vast majority of other cloud apps who integrate do with user lists. It’s the only thing that makes sense as a team admin.
