Osgrid is back up, or kind of back up, not entirely convinced by it, from a performance point of view, but it's a good omen, and another promise of good times ahead is the start of the Advent build by Ange Menges and Nani ferguson. Ange and Nani have been consistently building festive, ephemeral regions for over 12 years in Opensim (and worked together before that back in SL) so they're used to the vagaries of the virtual. They have set up their latest creation Advent Calendar on two grids, Zetaworlds and OSGrid. 
When you arrive there's the usual poster board but this time, no HUD, it's just up to you to go out wandering around the snowy, bosky neighborhood and seek out structures with numbers on them.
