[Disabling Creeper spawn or explosions]

Hi,

I have a question, is there a mod that is compatible with no-creeper spawnings? or either way no explosions.

I have tried this mod, but it doesnt seem to work (still spawns creepers, and causes a lot of errors).

And is there a possibility to manage groups? Or at least disable /sethome for all normal users?

Thanks in advance :)
