So, while most of HW's devs are rather opposed to social media, the game has few of them maintained by community, but they lack visibility. You have to guess if Hedgewars might have e.g. Discord server and search for it on the forum.
So I suggest that there should be some "Community" tab on the top, with links to other community channels. Here are the links to stuff I know about:
Discord https://discord.gg/sURxug4
Facebook https://www.facebook.com/Hedgewars
Twitter https://twitter.com/hedgewars
Reddit https://www.reddit.com/r/Hedgewars
ModDB https://www.moddb.com/games/hedgewars
itch.io https://hedgewars.itch.io/hedgewars
Discord especially deserves mentioning, because it's a popular platform and few people asked about it. Facebook/Twitter seem to be somewhat active too. Reddid it pretty dead, but that might be because no one knows about it (also it was re-created?). As for ModDB and itch.io, not sure about them, but they exist too xd
Also if somehow the tab gets added, it would be probably useful to make a post about it. Also maybe it's possible to mention other community channels in game?
