I just activated the mingle forum plugin and followed the directions from the editorial video. After I created the category, I created 2 forums. Then I went to my blog and click on the Forum page which took me to a log in page. I click on the forum but it would not let me add a topic. Why is that for? Where on the editorial video shows " add a topic button" on my dashboard the option shows subscribe to get notifications. Can you help please?
