We're running Elgg 0.8.1 using SSL for the entire site and the walled garden. We have two configurations: the main one has the Folio, Forum, Bookmarks, Calendar, Presentation, Messages and Category Topics plugins installed. We've also implemented a 'hack' to get 'Flag Content' to work at all, by adding ' $functioninit?[] = $CFG->dirroot . "units/admin/admin_actions.php"; ' to to units/admin/main.php (this was apparently removed going from RC1 to the final version, according to an exchange on the Developer Discussion blog from back in July: http://elgg.org/developers/weblog/1023.html)
A second test installation just has the Folio plugin at the moment. In both cases, the administrator can't see pages or posts that have restricted access beyond 'Logged In Users'.
This makes it difficult to administer flagged content or generally to monitor the site.
