Welcome to AlterSMP, the SMP for very cool gamers.
We have a pretty cool community, like, it's not all that big but it's a community and it's a nice one.
We have MCMMO, which allows you to gain levels in certain skills (eg. mining, alchemy, acrobatics, etc.) by doing everyday Minecraft tasks. You'll be able to unlock special abilities and perks for levelling up your skills and it's a great way to keep track of how much you no-life the game (because we all do sometimes). It's also good to compete against friends to see who has dedicated most of their life to the game, and seems to have no other friends due to their incapability to socialize.
Anyways, 1.18 is the big thing here, I mean, we're one of the first servers on here to officially update properly to 1.18, all bugs and plugin issues were mostly ironed out in the first day or two so there should be nothing to worry about.
