I'm getting married August 2018 and was wondering when is a good time to start collecting addresses. I am planning on only sending Save the Dates to out of staters and family members, since most of our friends know the date already. My plan was to create a Facebook group (which could also be used as an informal save the date) with a link to put their address in, as well as put our wedding website in this group. I'm just not sure when is the right time to start doing this since we are still a 10 months out. I think I might be overthinking this whole process, but any suggestions and advice is welcome!
