This should make your page titles reflect the section you are in. Its a bit ugly because I don't know the correct syntax for if and else if statements in Ruby so if anyone sees this and wants to make it neater please post a comment.
I've been struggling with getting Mephisto working on DreamHost shared hosting but I think I've got my head round it now. I followed Labrat's excellent instructions but being a RoR newb I still struggled and haven't fully understood the implications of what I've done. The only major modification I made was to use a different dispatch.rb file than the one supplied with Mephisto. I've attached it to the article in case anyone feels like using it.
