You got me... I didn't realize that they were hot in recent times. I am an SEO Pro, and since SEO experts and such understand the Internet, and there are so many good names available to register, I wouldn't think so.
However, IF you can keep SEOphpBB.com updated with the current information on how to optimize phpBB, I know the site would be valuable. But optimizing phpBB is a huge mess and hasn't worked with the latest versions. Plus, phpBB poses security problems that have never been addressed, simple issues with the interface, piss-poor IP logging and reporting, piss-poor ban tools, etc... Plus it offers no out-of-shelf optimization techniques like vBulletin.
But, I have learned the hard way.
Good Luck with It! -Doug
