[development] Privatemsg needs a better maintainer

[Naheem Zaffar]

Thanks for the info. (I am using the patch on one of the issue queues
(with unneeded/broken features commented out) on a live site, but with
little activity for a while, was starting to get a little worried.)

I do plan on trying to help out, but there are bits I have no
understanding of. (I have looked at the code, helped in a previous
patch etc.)
