When you create a new server, Do you have to add ranks? I mean, do you just do /addrank or /rankadd or something like that? What is a good website to get texture packs from? I am also confused about the cmds that certain ranks can use...

Point is, I am still confused.  

You can add ranks from the server's configuration files. You can find texture packs on many different places, such as doing /mi env on maps or looking through collections online. To change command permissions, use /cmdset

ok thank you soo much!!
