My daughter got a bridesmoogle from attending mine & Hubby's "anniversary", if that helps. I wish I could have the minions too, all things considered. Seems a bit silly not to - when I got married for real, I made thank you gifts for the attendees, but also kept one of each gift for us for our memory box, and that box gets added to every anniversary.

Haven't ever seen random invites for weddings on my server, but I haven't exactly looked either.
