Comment 3 for bug 419965

Tom, I didn't see your comment when I triaged. I agree with mpt here; subscribing is editing only from the DB point of view or in a metaphorical sense. To ask someone to subscribe is more a call to action, like the plus icon implies (though honestly there are metaphor/language breakdowns there, too).

The edit icon seems appropriate to me after someone is subscribed if the action carries the person to an edit menu or AJAXified overlay to adjust subscription settings. I've seen this on branch pages, I believe.
