Title: Add autoannouncer or something similar to lobby. There are alot of new ppl during the day that join lobby, leave some time later and are never seen again. Just add a auto message or something like "join the discord to find out when games are going" or change the motd. every 1 or 2 days there are ppl (probably more often, just dont see it in steam-serverbrowser) and imagine that would be all new player for empires. I suggested this a few times but not here i think. Also this would be like 2 minutes of work.
