The wiki I am most active on is struggling with that too. I have noticed that recently, anonimous users became able to post on the new message walls (and even trigger notifications). So you can make an alternative account and use it's wall as a forum board.

Edit: Also, there are Wiki-style forums which are open to anonimous users. They are not as convenient and intuitive as the retired forums but you may get used to it.
