Thanks for the confirmation Tanktalus. Being relatively new to PM, with few votes, I do try to think about where to use them. As to the importance of XP, it seems a nice, low overhead way of encouraging courtesy and constructive comments, both of which are exceptionally high at PM. Some of that's the Perl community norms in general, but the XP system has a role in it as well. Beyond that, I agree it's good not to take it too seriously, as there will be considerable noise in any such system of human opinion.

My post was just looking for confirmation that the technical aspects were working, and you gave me that clearly and concisely, thanks again, and thanks to others as well for their comments.
