 == Rated R (Rihanna album) == 

 Greetings.  I noticed that you and  had reverted each other's edits back and forth numerous times in the last couple of days.  This behavior constitutes edit warring and is best avoided.  Except in cases of clear vandalism, the WP:3RR guideline limits you to 3 reverts.  In this case I suspect that the other editor may have been looking at US-centric release data and possibly was not have been aware of the earlier release date.  A simple note in the user's talk page or a more descriptive edit summary may have resolved this much sooner.    / "
