In !newcastleupontyne@lemmy.world we have a list of other UK communities in the sidebar. It might be nice if we can get a comprehensive list of the other UK based communites too, so if you run one or know of one, drop a link here. Make sure it's in the remote format so that they can be reached from any instance - this is !<communityname>@<instanceurl>. I don't think hyperlinking works properly yet, but there are active issues raised on the github to get it functional.
