If your wiki doesn't have a Forum, you won't be able to enable it because Wikia is switching to Discussions, and the highlight function in Discussions is being worked on.

Do you need to add "Recent blog posts" into the sidebar on every page or just the main page? If the first, you could try using AddRailModule and if the second you could use the bloglist tag along with main page column tags.
