I'm sad to report that DnD Tools is officially on borrowed time. Below is the latest commentary pasted straight from their site.
End of an era...

Bad news my fellow gamers…
Wizards of the Coast has sent us a Cease and Desist order.
As a non-profit all volunteer we have neither the means nor the know-how to properly fight this litigation. As it stands we are in the process of shutting down the site.
We will no longer be adding any new information so please do not send us any more comments to fix pages or requests to join our contribution team.
Unfortunately, we do not have a specific date when the site will be shut-down, but it will happen.
Best regards,
DndTools Team
