As of this morning, the TrotCon online convention has begun, with the usual PonyTown tie-in. Tomorrow and Sunday will both be filled with panels and festivities throughout.
For general Trotcon stuff, you can head to their website for the schedule and things.
And for PonyTown, the event server is where you want to go. We are currently hanging in the cave if anyone wants to come say hi for the next hour or so. See screenshot above for that.
