I host a server and want to be able to combine PE users and PC users. I have heard of some software that will allow you to host a minecraft PE server on your computer.
IT IS NOT POSSIBLE (WITH SPIGOT/OTHER PC SERVERS)
The software/plugin you probably heard is Big Brother. It allows you to combine PE and PC users on a single server.
1) it is kind of old, and might not work on your server.
2) It runs on MC:PE server, not MC PC servers.
