My company does not have a Company Forum for current clients, or even pre-clients to post in. When I started - I had one, however it wasn't used much and then I decided to drop it, as clients preferred to have quick and efficient support via the helpdesk and e-mail.
What is more, it also depends on your company image. The larger, and the more "corporate" the company, the less likely you are to find a support forum. Dell doesn't have one, nor do many other very large companies - only one company I know of is SonyEricsson there is only one staff member, who barely ever replies. Today it would seem that the better the image of the company, the less likely it'll have a forum board - while unfortunately the lower the image, the more likely.
Personally, I don't see anything wrong with a forum board - as long as it's active, and very active at that, and also as along as the staff actually post and reply to all questions. However something difficult about having support forums is to make sure that people do not post their account information such as passwords and so on; which is why support via a Help Desk or e-mail is much better.
In regards to what boards allow guest posting, I'm afraid to say I have not found one forum board that does not allow guest posting - and I know of over 40 different forum boards.
