Create a command that if the person types receives this position, for a certain time;

Where to find an addon to create a command that if the person types receive such a charge, for a certain time and after he tries to use it again, it will not give because the use is unique.

It's possible? Where can I find an addon, command that personalized way?

hmm. Never heard of an addon doing that before but that sounds very easy to program. Give it a shot man.
