It would be really helpful if Spaces included a widget similar to the Group Overview widget.
This should be enabled/on by default and perhaps something Site Admins could disable removal of. Having the owner and a description would be really helpful for a lot of folks who don't take the time to use a Formatted Text or other widgets to "announce" the purpose/ownership of spaces. Probably wouldn't use the 'group type' field, with the created date something the Space Owner could configure.
Thanks for the feature request, it is great to hear that you're finding the Group Overview valuable enough that you'd like to see something similar in Spaces. This request is filed as CS-13398.
