In Phabricator, I want to create a project inside a space or want to assign an existing project to a space, but I can't find a way to do so. I want to make sure whether or not I am missing something before creating a new task at Phacility.
Update: I found the closed task T8493 that is dealing with the topic and I created T10254.
There is no way to assign a project to a space right now, see the tasks on Phacility mentioned in the updated question.
But there is a way to deal the problem I use: I have "parent" projects for the teams in our company. No one can join or leave those projects, only the admins can manage memberships. Then we have different "inner" projects that are visible and joinable for the members of the regarding parent project. The repositories and tasks are then visible for members of the inner projects. Users can choose which inner projects within their team area they need.
This way one could also deal with more than two nested levels.
