We plan on sending out save the dates and having everyone rsvp online (don't tell me it's tacky, we're doing it). I have a few questions about this process though... when do the save the dates go out when doing online rsvps? Our wedding is Memorial Day 2015, and everything I have read says 6-9 months in advance for stds. Also... the wording... since stds usually say "formal invite to follow" how do I get the point across that we're not sending them out? Thanks!
