Diablo Wiki is always in need of helpful members of the community to update the content and keep it as current and useful as possible. If you wish to help but don't know where to get started why not help with any of the following projects:
DiabloWiki is a great resource for everyone, and is built by members of the Diablo community adding small or big contributions. Time or English skills are not constraints that should keep you from signing up to the project, as some members might have plenty of time but using English as a second language, and others have skills but only time to correct grammar!
Your account will work on both the Diablo 2 and Diablo 3 wikis here at DiabloWiki, if you sign up on one of them. If you have an account on any other Diablo site, such as Diablo: IncGamers, you will not automatically be able to use that username; you will have to sign up for DiabloWiki separately.
When you have signed up, this is how you get help:
Our homegrown Help section includes almost anything you would like to know.
The Wiki Markup page is great if it's a specific piece of "wiki code" you need.

The Diablo 3 beta is due to begin before the end of September 2011. It will be a closed beta and will be aimed mainly at testing the Battle.net server infrastructure, Blizzard's launcher and patcher software. The beta will contain a very small part of Diablo 3, not even the first act in full, however it will contain all five classes. There will be no open beta (where anyone and everyone can test) and to be in the running to be selected for the closed beta you must have a battle.net account and have completed a beta profile.
