Last night Ning, our social network hosting platform, pushed out a few new features and in the process changed our look and feel a bit. Among those changes: the "Add a blog post" link at the bottom of the blog listings and "Add a discussion" link at the bottom of the forum listings are gone. So now how do you do those things?
Answer: use the tabs above. You add a discussion topic
on the "Forum" tab and add a blog post
on the "My Page" tab (under the "My Blog" subtab).
This isn't ideal, and I assume it's just temporary until Ning rolls out a more flexible layout toolset. But in the meantime, the tabs are your friend ;-)
