I've installed Q&A to test to see how it may work for my 3.1.1 multisite installation.
1. I uploaded via ftp and activated in main site.
2. I created a custom menu via link to mysite/questions/ask.
3. Configured settings for users.
4. Added some categories.
5. Went to main page - clicked on the menu and got a 404 error
What did I miss? By the way, I am trying to understand the functional differences between this plugin and a forum plugin? They both provide user asked questions and responses. Is it just in the ratings aspect?
