If you are just making one locked post with no replies then WordPress will suit you better. Forums are best for users being able to start threads themselves. Blog-like CMS software is best for 1-to-many.
The other benefit of WordPress is that you can have unlimited alias nicknames and anonymous self-posting with alias nicknames. So you could pretend to be “Microsoft” when you post and then later if Microsoft really becomes a client you can give them a true login with the real username.
Last but not least wordpress has far more development and plugins and contributors than bbpress at this time. Something to consider for a commercial application.
