Okay thanks, I was just wondering on your thoughts behind this - I've just never seen this type of board used before.

Actually I believe VBulletin can be switched between a flat and hierarchical view though not quite like this with the frames (I don't think?)

I can appreciate your desire for "intimacy" with your users here - this msgboard does seem to fill that one-on-one kinda feel. I believe that can be achieved similarily with Drupal or blog software but like you've already said, this works nicely for you as is and probably ain't nearly as complex to setup.

Thanks for answering...
