I have been using another membership-program DAP but since that don't handle Multi Sites I am trying your plugin.
It looks great BUT with DAP it was so easy to have completely different Nav's there many pages don't show up until you are logged in. s2Member show ALL pages and then when clicked on in the Nav it redirects to Memberlevel. That was as DAP was a year ago, now it handle that really nice, but only on one site.
Have looked on your advanced settings BUT I can't really get out how to "hide" the pages until member is logged in.
Take care / Lars
