Etiquette for Playing Online as a Team

Hello.

Sorry if this is the wrong forum.

TLDR: Is there a way I should name the game that I host to indicate this? Is there some sort of etiquette I’m not aware of that I should know for this setup?

Me and my friend have picked AOE3 back up during COVID times after playing it in middle and high school from about 2008-2012. We’ve been playing together 3-2 against Hard AIs, and winning consistently. We also square off regularly against each other to experience going against a human player. We’ve been doing so for about a month now. My friend is the better player of us, and plays the Dutch. I play Russians in general because every once in a while I can pull off a strelet rush on him.

After we played tonight, we discussed the possibility of setting up a game where we play against 2 human opponents on ES Online as a challenge for us both. We’re two guys who really like the game, and want to get better at it through playing against other players, but we don’t know if there are some unwritten rules to playing nowadays.

So, my question is twofold. Is there a way I should name the game that I host to indicate this? Is there some sort of etiquette I’m not aware of that I should know for this setup?

Thanks very much for any help.
