  You talk like that's a bad thing.  I say that's /exactly/ what we *want* to happen.  Then the users will go beat up the CBCP
provider instead of coming and flooding the list with offtopic requests for support for a commercial product.  :-D Sounds like a
win-win to me!

  Yay!  Even better!  3PP fight!  As long as they're fighting each other they're not giving us any hassle!
