do what i did and hand them over to another designer - I don't have the time or inclination to port all of my themes (12 in my case) to phpbb3, and I also have no confidence in the whole forum concept having much more of a lifespan. Forums attract trolls, moaners, whiners and above all else spammers/spam bots. Most people in need of web development these days avoid forum software and are more interested in blogs/comments and support areas.
