However this will leave the chest unprotected, which means someone could come along and make it private to themselves. And I believe also break the chest if they want. Not really a problem on this server but, it is something to take note of.

Really what you have to do is, use both
/cremove
then
/cpublic

and you can check the protection with
/cinfo
