QUOTE said:Nintendo has announced that June 25th is the official Nintendo 3DS StreetPass Day. They’ve setup a Meetup Everywhere hub that allows groups and fans to organise StreetPass-based events around the world. It’s great to see official support for these events, so you may want to set aside time on June 25th.

Not sure if this is posted, but this event is awesome for collecting StreetPass tags.
