Hey, this is my idea! You clearly took that from me! You can check my group for the news articles over a month old talking about the idea, and you have posted in topics where I talk about it!
Oh well, I'm not mad at you. This is actually good; spread the idea!
I was actually going to message you about the idea and ask if you wanted your name on the first post. But looks like you got to the thread first. 
I don't understand... co-team matches? Please explain. Sounds cool though.
No problem. I already have two alliances going, but chess.com doesn't have a feature where the two teams in the alliance can team up for vote chess or team matches. That is a great idea though, and I hadn't thought of alliances allowing that. It would be great if that could be done!
By the way, is there a place to send suggestions regarding groups? I have a couple more suggestions, but don't know where to send them. Do I just make a forum topic?
There's a suggestions thread. I just wanted some public opinion before I posted the idea on it. Can't find it right now, anyway.
This is a possible new feature for chess.com. The ability for groups to join together, forming alliances, and then being able to play in special co-team matches where anyone from each alliance can join. This could be an interesting idea, especially for country teams where you can only belong to one.
I think it's an interesting idea. How about you guys?
