Re: invitations
You do not have to send save the Dates but if you are planning to send them I would do it in the next couple of months if the date on your profile is accurate. As for invites they are usually sent 8-12 weeks in advance- I sent mine out closer to 12 weeks before b/c we had a lot of out of town guests...some of our invites had to be sent internationally so I wanted to have extra time.
