I am not convinced we need a dedicated space for teams quite yet. Community feature requests and team feature request are welcome in the feature category. The merit of a #team category would be a space to discuss team usage of Discourse more openly, not a place for posting bugs and feature requests. We need more of this discussion going on prior to creating a dedicated house for it.
Discourse is a lot of things to many people and teams feature requests are welcome here just as are public support community feature requests.
This specific one, to me, feels a bit premature.
For one @nbianca is in the midst of refining the bookmark list to support a mode where your bookmarks operate as a TODO list and you have to explicitly remove bookmarks to mark them done. Once we have that, maybe we can start exploring ideas of sharing bookmark lists… eg an option for, hey my bookmark list is my TODO list, share it with everyone, I am OK with that [ ].
Now is not the time for this, quite a few things need to happen first.
