Important Update

The entire 'dev.ryzom.com' website will be phased out in the coming months. The site has been put into read-only mode for non-developers and the content is in the process of being moved. Our new home will be: www.ryzomcore.org - which you may recognize as what used to be the developers blog. We have moved the source code to BitBucket already and merged the SF.net repository over, it will be left in place for history for some time. In addition to hosting source our issues will be hosted in BitBucket for the time being. We have an OnDemand license for JIRA but have decided not to use it for the time being. For forums and discussions we will be using Google Communities. Here's a recap of the new sites we will be using:

Moving all of the wiki content will be a slow process and any help would be greatly appreciated. Thank you!
