How can I watch/control what is going on with a label on JIRA OnDemand?

Question

I am labelling stories in JIRA that I am considering for inclusion as a Minimum Marketable Feature Set. I don't want anyone to delete a particular label I've added without me knowing. I don't want them to add it to any other stories without me knowing. Ideally I don't want anyone making material changes to a story that I've labelled without me knowing. Is it possible to do something that is effectively to "watch" a label, so that I'm notified when anyone updates a story with label , or when anyone adds label to a new story?

In fact yes, the plugins can only be installed on the Download Version.

Thanks Ramiro.  Unfortunately I'm using OnDemand, and this sounds like a solution for Download... right?

There's a type of listener you can add that it is called 'fire an event when condition is true' that it can be picked up by a notification scheme, or there's another called 'send a custom email' when a condition are met.
