I would only need a single topic area, in my past experiences with forums software they have multiple posting areas. It might look a little empty in a forum layout if there is only one topic area… my web host has PHP BB as one of their installed services so I guess I will take a look at it. Thanks for sharing your positive experience with OSQA, good to know that it is a reliable script.
Does anyone know whether an OSQA based support area would give my site good visibility to search engines versus a blog versus a forum? Right now I have informational pages with technical info and those pages get the most response from search engines, so I believe that a discussion page in some format that covers technical issues for the products could be excellent for helping to get the content in front of people who need it. I just don't know whether there are pros and cons to the different methods of presenting this material as far as SEO goes.
