Apparently, even Apple doesn't think this "wiki engine" OSX Lion Server classifies as a server. While filling out feedback at http://www.apple.com/feedback/server.html on how dissatisfied I am with this "server" offering I noticed that the area for Which version of Mac OSX Server are you using drop down list does not have 10.7. Attached is a screen shot of that drop down. What they don't like Auto-Save either?
They seem to be frequently late in updating the feedback page. When Lion (client) was released I couldn't select 10.7 from the pulldown either, and then with the 10.7.1 release I couldn't select 10.7.1.
