I had the same problem, when I first started playing, seems all the server with people get further down on the list, try holding space or scrolling the sort by number of players. Hopefully this helps you too!
completely new to mechanical keyboards and therefore got no knowledge on where to buy customized key caps. Anyone got some good sites to refer too.
Both pre-made and customizable are something I am looking for. No idea if either are necessary, but I am using a Filco TKL and location is Norway.
