We do plan to roll out PM use by the end of the year, but we are looking to clean up some of our spam accounts and other elements of the site first,
We are late to roll out PMs, but this is high on the list of things we wish to do, as long as it is not abused.

So please keep tuned and we are open to all suggestions, thanks everyone in our community, and I promise there will be LOTS of nice things in the pipeline!
