I made a group for SICSA to act as a test... and put in an intro page which should be on a new SICSA "Book" (which seems to be the Drupal term for Wiki I think) . But when you go to the group page, there are no links to content other than Blog posts for the group. Maybe more ticks in the config boxes for groups are needed? Take a look at http://groups.drupal.org/secondlife for example which when a user is logged in lets you crteae Wiki pages (and it uses the term Wiki rather than Book), diary events ona calednar, polls, etc. for te group.
