Hey
@WoolooCupcake,
You can join the server using the official minecraft java edition launcher that you can find here
https://www.minecraft.net/en-us/download.
Once you have minecraft downloaded, you can select version 1.12.2 on the launcher which is the preferred version to use for Potterworld. You can follow this guide to select that
https://help.minecraft.net/hc/en-us...hange-Game-Version-for-Minecraft-Java-Edition.
After that you can join the server using the following tutorial
https://help.minecraft.net/hc/en-us/articles/360035131391-How-to-Play-Minecraft-Multiplayer under the "
Playing on an Online Server" section to learn how to join minecraft servers.
The IP for potterworld is "play.potterworldmc.com".
Let me know if you need any more help or get stuck with anything else.
Regards,
Frost
