HoMMWorld is undergoing a rebuild. This will refresh organization of existing content, and bring in new content as well. There will also be some user interactivity options, such as a discussion board and a blog, and a new design to visually unify the various sub-sites.
There is no set timeline for this process, but hopefully it will not be too long. If you are interested, you are welcome to follow news and developments on Facebook and Twitter. You are also welcome to sign up below to be notified of any significant developments.
