Adding Website Workshops Forum

I’m looking into selection of a forum (bulletin board) for use with Build a Website Workshops as well as for my WordPress plugin. For Workshops I want something that integrates nicely with Joomla! but I may choose something different for my WordPress plugins since it needs to integrate nicely with WordPress 🙂
At first glance, Joo!BB looks attractive. However, forum.joomla.org uses phpBB. I’m guessing that this might be because they selected phpBB long ago, and it doesn’t make sense to switch even if there are better options now.
I’m going to try installing joo!BB on my BuildAWebsiteWorkshops.com site and see how it works.
