I agree and add my two cents
Every server has unique communities and unique issues, event bugs, dynamic positions, times and places…. so discussions relevant to any of those things are totally relative.
At the very least there should be a tag, option, dropdown, flag, icon or some other very obvious way at all points of viewing a post or thread to see what server it is relevant to or if it is relevant to all servers!
please add this sooner rather than later
