So in my plugin, my Config.yml basically looks like this: Code: MasterBugPatch: key: fa9ej redd1t: key: ka0e9 What I'm asking is two questions: 1) How can I check to see if Masterbugpatch or redd1t exist in an if statement? 2) How would I be able to set a different key or get key from usernames? I do actually have most of question number two but I would really like to know the proper way to do this . Thank you! I'm looking forward to any answers One more thing to any developers who want to take the extra step to help me. Code: Masterbugpatch: key: - Key1 - Key2 How would I make a listed feature live above? How would I add on to the list, edit list, see what their list contains, etc.
