The subscription widget in hubs/widgets/subscriptions.py currently lists what hubs you belong to and what hubs you subscribe to.

The text reads like this:

Belongs to: infrastructure and ralph

Subscribes to: designteam, i18n, and marketing

It would be cool if 'infrastructure', 'designteam', 'i18n', 'marketing', and 'ralph' were all clickable links that would take you to those hubs.
