Pretty much what Mardoc said.

The colors on the score tab have been changed as well though, so it's pretty easy to know who's who.
Communications with Adlain are going well so far. After exchanging greetings, I asked about the available scouting paths (the mountains would take me either right next to his border, or make a detour around them), and Adlain immediately offered to let me take the faster route. I found this while doing so:
That's a pretty gutsy play when a Warrior from a Civ you only just met is near.

I guess that the path Adlain proposed means I won't ever be in a position to threaten the settler, but still.. anyway, I think I'll want to keep him on my good side. He also mentioned there's a scout from Locke and Cervantes a bit to the southeast. I guess I know where to go next.
Second cities are becoming more common too. At this rate I'll be one of the latter Civs to expand. D'oh.. I do plan for city 3 to follow soon after that though.
Mackoti came through with the map exchange after a slight delay (he had some hardware problems). Interestingly, he sent me a batch of unedited screenshots, showing me a lot more than just defogged tiles. Most interesting was this one:
Mackoti, if you later read this, you should really crop your screenshots. This tells me so much more than you probably intended to share.
Hello beautiful terrain! I will be wanting the lion's share of that for sure. Since the screenshot includes the minimap, I know we're not that far removed from each other, so expansion will head east for now.

Possible city locations are 1NE of the gold, and 1N of the cows. Cities further east than that should be doable too (although I'll probably need some Bowmen to defend those).
Mackoti also mentioned having met Luddite to his east (his borders are barely visible on the minimap), and it looks like he's met LordParkin as well.
If that earlier map placement theory is correct, it might look something like this:
?? - SleepingMoogle - Mackoti/Ioan - Luddite - LordParkin?
JUNGLE JUNGLE JUNGLE
?? - Adlain - Locke/Cervantes - LordParkin? - ??
Locke and LordParkin's placement could be wrong, but this probably is most likely. Perhaps I can confirm or disprove this through diplomacy, but top of the list for now is to try and figure out if either of the Civs I met has early wonder plans.
