sorry, i'm sure this has been asked before but i've been looking and can't find it.
we have family in europe and some friends living overseas. i know many of them already know our wedding date but some do not. i'm definitely not expecting people to travel, but our families are pretty close knit so they actually might.
should i mail their std's and invites earlier than everyone else's, to give them adequate time in case they want to come? should i wait until the standard timeframe? or should i mail everyone's out a little earlier, but all at once?
we're not sending things out just yet - i just have some time on my hands now and i'd like to get as much of this prepped and ready to go as possible. that way when it's time, i can just drop them off at the post office.

thanks for your advice and hope everyone's planning is going well!
