Hi Sean Molam,
Thank you very much for providing this feedback. Setting the Guid of the forum to display for the SingleForum control will be implemented for our next release - Sitefinity 3.2. Also we plan to provide more granular permissions for all modules, not only forums, but we cannot promise when they will be available. This means that you will be able to configure permissions for separate blogs and forums.
Right now the Forums module is not based on Generic Content and many features available to Blogs and News are missing. We will change that for the future, but it will not make it into 3.2. Of course, when that happens, it will get URL rewriting and also become SEO friendly. Thank you for the suggestions again, and excuse us for the inconvenience.
