I'm in! Wine writer/educator, would love to be a part of this. I spent three weeks in Mendoza and could definitely be of help when it comes to teaching others about Argentine wines/wines in general, and I'm not pretentious in the least. I promise!
Shameless plug... I have a blog about food, wine and travel... it's not BA related but considering that I've been living here since October, it definitely has a significant amount of BA/AR wine posts...
