I don't know exactly what mods he has installed, there are a lot that expand the managability of the administration panel, some added options... if you want, I can go into the admin panel and take some screenshots for you.... or, I can just wait until he gets on AIM and I can ask him if he can even remember all the mods he installed. I do know that he got them from one of the links from phpBB's website.
Anyway, hope that helps.PS-If you want to check it out, you can see some of the mods from a Registered user level if you just go to the forums,
