We now have a blog feature. This feature is currently being developed and tested by Wikia, and only available of a few wikis by request.
Blogs are a new type of article with a single author. They can be used to write fan fiction, community announcements, top 10 lists, opinions, queries, etc. In other words everything and anything unsuitable for regular articles. You can also have your own avatar.
Blogs can be edited or deleted just like any other article, in case of abuse or vandalism.
If you want to use and learn more about blogs, refer to Help:Blog article.
I hope everyone enjoys this feature, and don't be afraid to use them.
