Design Calendar
An open calendar for people to submit events, contests, awards ceremonies, etc. Things relating to design and timelines.Premium listings for paying sponsors. Make it a site in its own, but with a widget that people could put on their sites. Could maybe even do a Google Calendar integration. Spit out custom calendars for people in custom areas…
This could also then become a hub for posting contests, call for entries, etc. You want people to submit to your HUGO BOSS design competition, well then you need to put up a listing here.
