Name the object to the UserId of someone you want to make an admin.
The default keybind to open the menu is BackSlash. To change the keybind, go to the GUI and change the KeyOpenBind attribute. (GUI is located at BanGUI By Dude8074 >> Scripts >> BanGUIManager >> GUI Mover >> banGUI
PLANNED FEATURES
Menu themes (Coming in 2.0.0.B!)
Player info tab (Coming in 2.0.0.B!)
Punish by UserId, suggested by @EmbatTheHybrid (Don’t know when this is coming. Sometime between 2.0.0.B and 3.0.0)
FEATURES
BanGUI features server-side UserId validation for any RemoteEvents on the model.
UPDATE: I have discovered a bug in the Roblox Player, causing the GUI to load in Studio but not the player. This issue is fixed and the model file should be updated shortly. View the full changelog with the link in the post.
I have fixed the security issues with the model, and now there is a verification (Checks to see if the person who fired it is an admin, with UserIds) for anyone who fires the event.
You can now ban players only from the server, using the Server Ban button. (Note: You must reinstall the module to get this update. I will make an autoupdater plugin soon though.)
NEXT UPDATE IN POLL
Edit: the custom modules update has been delayed, due to my brain failing to come up with what it would be used for. (Well, you could submit your ideas i guess, by replying to this.) Sorry about that!
