The Scraps "weekly game" is happening again this week, where everyone is invited to join the multiplayer at roughly the same time to get some people on playing together.
The main one is again at 8pm EDT on Saturday (that's midnight UTC). But if that's out of your timezone or you just want to play twice, try coming on 12 hours earlier at 8am EDT (midday Saturday UTC).
I've added both to the Steam events calendar which should also auto-convert to your timezone: http://steamcommunity.com/games/350150/events
Last week was a good time:
