There's two features that I would absolutely love to have in EO.
1) An RSS feed that will post the event a week before it is set to start - this will let me post a link to the event on Twitter reminding people to show up or book tickets for the event.
2) Mailing list summary. I would like to be able to have a weekly or fortnightly email which summarises all the events coming up for the next 4 weeks.
I've been wrecking my brain trying to find something that can do parsing of the .ics file for both of these features (which I guess would be the ideal solution) but haven't been able to find a solution so far.
