As part of the rehaul of Spread Firefox, I'd love to take a look at the events hub and how we can make it more user friendly and inviting.  The whole goal of events is to celebrate community and evangelize Mozilla and Firefox.
I have shared some ideas below, but would love to hear yours as well.  I have noted changes that are technical and user experience focused, as well as content related.

• Creating/Adding Events to the calendar:
  • Instructions: Add some basic instructions on how to add events to the calendar, join events and post comments.
  • WYSIWYG editor:  It would be helpful to have it here as well for quick calendar additions and for folks that that don't know HTML well.
  • Start times:  Currently, the default start times for the events are a bit arbitrary and I think it would make sense to have them default to 9:00 a.m. until a user changes them.
• Viewing the calendar:
  • Filters:  It would be great to be able to filter events by
    • Continent/geography
    • Hackathon
    • Localization
    • Campus Rep
    • Anything else?
  • Editing current filters:  Foo and Bar events need to be removed ;-)
• How to get involved with events:
  • Become a Speaker:  We need to round this out with more information on how to start doing this, including speaking tips, presentation templates and actual Mozilla presentations (pending!).
  • How to host an event:  I think there should be a section on what types of events that community members could host and how Mozilla can help, as well as some recent examples
• Projects that may have events:  This is just listing official projects vs. correlating projects and groups with events. 
• Events Triage Call details: Provide an explanation/purpose of the call and call details on the main page.

This is just listing official projects vs. correlating projects and groups with events. 

More thoughts to come, but wanted to get the dialogue going!
