I found a vanilla Minecraft SMP that started a few days ago and it already has a solid playerbase. The world is meant to be permanent so you can build big stuff and keep it there.
Most people are in their 20s and everyone seems pretty chill. The staff also wants to run small events like civilization and some modded and unmodded events besides the main vanilla world.
They want more people so it can feel mid sized and so there can be more builds going up all the time.
