I am responsible for administering & supporting the Collaborator website however do not have access to log onto the website's host. There have been several instances where I would have liked to understand what the current uptime is of the Collaborator server / services, and I currently have no way of figuring that out without asking somebody (and even then I'm not sure how easy it would be to figure this out).
Based on this my suggestion is to add uptime statistics to the Collaborator Administration page so that users like myself can quickly verify that the services are running normally and haven't recently shut down.
