We also have a Report Post button (lower corner of each post - under the member info), we prefer that is used when there is a problematic post.
Reporting instead of an angry reply is a very good idea..
A PM is another option, to help clear up possible conflict or perceived conflicts, if you would like to try to work it out.
We prefer that any conflicts be worked out privately and not on the forums, and of course the Ignore feature is available if you prefer that option.
