					a) you get any permissions you have in any existing root forum.
					b) If you have "albumpermissions -> canalbum" you can create albums and photos.
					c) If you have adminpermissions->canadminforums you can create channels.
					d) If you can forumpermissions->canpostnew you can create all the other types
				2) If the forumpermissions doesn't exist or is empty, treat this as a new install. Take the permissions
					from the xml file, taking the id as systemgroupid.
				3) At root everybody can create private messages.
				4) 	For the blog and social groups channels, we have newly created usergroups with systemgroupid. Those two channels
				are specified in the xml file.
				5) For all other usergroups in those two channels-
					a) if you have moderator permission canmoderateposts, no record. Just inherit.
					b) otherwise, get your root permissions plus channel
				6) For the report channel- if you have moderator permission canmoderateposts anywhere on the site
					you inherit permissions. Otherwise you have none.
