I've search the site and couldn't find anything besides the chatbox on the bottom of the forum landing page. As great as that is, it requires people to be on the site to use it. I've set a Discord Channel (conviently named F.C Inter Milan).
For those that don't know what Discord is it's pretty much Slack for gamers. It has voice communication, and text chatting. There is a mobile client (Android/iOS), desktop client (Windows/MacOS), and a browser based client which works wonderfully. It's free to use, and the larger the community the better voice communication codec they offer. Discord also has bot support, so for the programmers out there we can create a "score" bot or others for the channel. There are servers in Amsterdam, Brazil, Frankfurt, London, Singapore, Sydney, and the US. I currently have it set to "US EAST" as I'm the only one in there, but the more people that join we can gather some intel and decide on a central server so everyone doesn't lag like mad.
There are a lot of people registered here. This chat does not take over the forums, as I plan to set to allow only links to the forum/subreddit. I hope this is fine and if so, that you all join. There's still work to be done but people can idle there and if anyone knows python/java/C#, feel free to work on a bot and I'll invite it.
