Perhaps tutorial isn't quite the right word, but with time it will expand. If you ever though of adding something to the wiki but didn't know how to, you might want to take a look at this page. And if you do, come back here and tell us what you liked or disliked about it, and what additions you'd like.
In other news regarding the wiki, we've set up a small fan-fiction section set up. As the fan fiction forum here at Diablofans developes, so will the wiki. In the end it will hopefully be an easily navigated page for all those wishing to find a good diablo read.
In the last week, we've also received three new builds in the wiki: A Werewolf Druid written by Zhar, a Bowzon guide written by someone called Muroidea, and a Frenzy Barbarian guide written by Rousse. I hope all of them will receive future updates, and that we'll get more of the same kind in the future.
