Probably not, but it depends on what your site will need. Is the basis going to be a forum? Or will it have nothing to do with a forum? phpBB is after all a bulletin board software, and unless you think you will need some bulletin-board-aspects for your site phpBB might not be the best choice for you - custom coding it or using a specific script might be better. However, there might be MODs that might accomplish what you need if you will be using a forum
