I have to admit that I’m really tired of people “raining in” the downloading of music to their networks. I mean, not only is downloaded music a complete annoyance for companies, but water + networks = total badness–trust me, I have experience with this one.
And I’ve only seen people try to reign in their users once or twice. This one almost makes sense if you’re looking at your network geek as a king or queen. But almost does not an idiom make.
So the saying is to “rein in” a practice that you wish to restrain. Got it? Excellent.
