We are trying to partly use Discourse as replacement for Basecamp. To that end, we have small groups that discuss in private categories.
I’m using a customised “watch category plugin” that makes users of a group watch a category automatically, thus creating a kind of mini-mailing list.
But one very useful bit of UI that Basecamp has is showing the members of a Basecamp at the top:
I would like to ask for an optional list of avatars derived from the category’s permissions to be displayed at the top of a category. This would help bring to mind the relevant audience and (the hope is) improve discussion.
This is related to the same issue for email.
