GameModeSign

[UnholyDecimator]

I was wondering for a while about the use case for this plugin, why couldn't you use the regular "/gm" command. It took me a while to realise what you were after: with your plugin, players are allowed to change their gamemode inside a single world, but they still cannot change their gamemode in other worlds (unlike what granting them the changegm permission would have meant).

That is correct.
