If you're looking for classic experience with quality of life changes, give this server a try. Love the master account system, you don't have to input your password everytime. And their security is probably one of the best out there. And they support Linux too. One admin is very active in discord, however I don't always like how they interact with their players. Someone was stuck in their halloween event puzzles, and they replied with "Thinking usually helps.". Take that as you will.
