As a viewer of the about dialog I can get some statistics to be informed about the usage of the server installation.

This is not an "obvious" feature. Its more like an eater-egg...

• In the About Dialog, the 4Minitz icon should be clickable
• On click on icon show a new section above the main contributors. Heading "Server Statistics" with some statistics table below
• Stats should show - from a server perspective:
  • Number of meeting series in DB
  • Number of minutes in DB
  • Number of users in DB
• Client renders the JSON array to a table and makes no assumptions on number of rows
• Server should provide a meteor method that produces "stats" result JSON as simple array with simple "string => value" pairs.
• No serverside "user login" check required. Even an anonymous user should be able to get stats

IMHO: Small eye-candy feature. No unit/e2e-test needed here.
