-Should guest list be private? From other guests? No, or at least not a priority item. -Should there be a +1 option for users? Should be some way for guest in the group to add anothet guest. "Hey, was just talking to Brenda this morning and she wanted to join us."

-Should there be a response time limit? And Should there be a email date reminder? Don't think either of these are something you need to worry about for 1.0. -Should there be a calendar.ics file download? Definitely

-Should there be a SMS notifications feature? I think you should work this or something similar in. Texting is sooo much more prevalent than email these days.

-Should there be a feature for multiple dinning option? -Should there be a invitee voting component included? More details on these, please.
