How can I change the voting command from "voteday" which is very long to anything else?
Thank you.

Unless the plugin offers a configuration or lang option for it, you'd have to edit the plugin directly. To do so, you'd find "voteday" and replace it with what you'd like. 

I didn't think it would be that easy. Ok thank you.

Well, it isnt that easy. :)
I changed every "voteday" in the config and in the language file to "day".
Everything that changed was the text not the command.
People still had to type "voteday".

line 438
[ChatCommand("voteday")] => [ChatCommand("anothercommand")]

Aaah I you meant the CS-File. Didn't think of that. Thank you. It worked.
