I am connected to G2G and everything is working I am able to find and download other player's AI personas and I see the one that I created is here on the website too so I'm guessing it's being shared with others. Plus I can share the link to it so others can download it but what I want to do is change my profile in game to a different looking avatar with different traits basically start over from default with a new guy. But won't that save over the one I have uploaded? Is there any way to make another one to upload? Also is there a way to be able to download all the ones I self create as AI personas to play against? Is such a thing possible? 

Other than having two Steam accounts that I play on I don't think you can view and download your own personas that you create and thusly you cannot just create a few to play against. You have to rely on other players created looks and traits they choose. Finding something you like.

I wish there was a better system to just be able to download and play against your own created personas.
