For those of you who are not already aware, wikia also allows the ability to create blog posts.
I haven't used these very much at this stage. But I thought it would be nice to let you all know that it is something which does exist and if you find a use for it, please make the most of it!
To make a blog post, go to your message wall, then select the 'Blog' tab, and click "Create blog post". Once you're drafted your blog post, you can also choose weather or not you want to allow comments (tick the checkbos in top right corner)
