Re: Integrating comments into forum
There is a plugin here called ‘bbPress Post’ that integrates your wordpress blog comments into your bbPress forum as topics for posts. Fel64 also ‘redid’ this plugin and has it so the posts are created in the bbPress forum from the wordpress blog and all comments are in the forum, but also show up in the wordpress post as comments as well.
Other software blog programs, I haven’t heard of any. Moving over to WordPress is a good option in my mind if you haven’t looked at it already since bbPress and WP are made and developed by many of the same people
