To subscribe yourself, there could be a link or whatever which just subscribes you to the bug with one click.
To subscribe someone else, doing what Launchpad currently does (opening an intermediate page) or even better, just opening a dialog to subscribe someone (like the dialog it's opened when you click on "choose" to change a bug to another project or package).
To unsubcribe either yourself or a team you are a member of, there could be a red (x) button next to its name in the Subscribes portlet which unsubscribes you/it in just one click.
I think there is three possibilities here:
* Subscribe yourself
* Subscribe someone else
* Unsubscribe

Does this sound like a good design?
