At the moment there are six questions tagged [rc]:

* Four are Unix/Linux questions, in which [rc] means [runcom](http://en.wikipedia.org/wiki/Run_commands).
* Two are Windows questions, in which [rc] means [Release Candidate](http://en.wikipedia.org/wiki/Release_candidate#Release_candidate).

I don't think tags are meant to be ambiguous in this way. What, if anything, should we do to keep this issue under control?
