Hi,
I am writing a plugin, and when the donor has a permission node, they will be able to change there prefix. I was originally going to just do this with PermissionsEx, but i decided to expand. Where do i find the lines of code i can use when developing a plugin? And what is the line to change the prefix?

Thank you!
