Originally, the site started out as WereTher, a small PHPBB based forum for therianthropes. It had about 100 members at its peak, and struggled to diversify itself from other communities. It was closed on 12/24/2010 with no plans of reopening. It was then reopened as Wulf Howl in its current incarnation.
Wulf Howl has a vast array of features not commonly found on other otherkin communities. Wulf Howl's profile system includes an "Otherkin Card"; a profile box explaining each user's theriotype(s) and personal experience with therianthropy. Wulf Howl also has an instant message and live chat system, a virtual currency, reputation and rating system, and more. Shiro has mentioned plans to eventually include a usermap, articles system, and a "seperate website which integrates with the forums."
Wulf Howl's administration is directed by an administrator (known as a Sheikh). The Sheikh appoints Praetors whom function as "Super Moderators" on the site. Praetors are in charge of overseeing Guardians whom function as moderators. Members whom have over 50 posts can apply for a Guardian position via an online form. Guardian applications are approved or denied by Praetors.
