Amazing work. *Installed*
Hopefully I'll be able to play with the plugin/templates so that it displays RSVP's from one calendar in one table and RSVP's from another in a separate table. I use one calendar for Attending Yes/No and another calendar for Buying Yes/No, so it would be odd to have all those in one table.
Or maybe that could be a potential upgrade to this hack? (Separating calendar IDs)
