I'm currently looking into implementing o3 Spaces as part of our ever growing VLP (I already have Drupal, Moodle and Sharepoint). It listens on port 8095 though and I can't work out how to change it. I have looked on the o3spaces forums but the changes I made based on the suggestions caused the site to just display blank pages. I am now unable to access the sites as their forums come up as blank pages too which is unrelated but annoying.
