The Englisc PeanutButter Wiki is an online Old English wiki resource currently under development by Rev. Bill Wōdenhelm. It is meant to be a collective source for an Old English language translator, dictionary, thesaurus, as well as encyclopedia, in the fashion of Wikipedia.
There is also available a basic Old English-teaching course, which is incomplete as of yet.
The site is not "final," therefore currently lacks a thorough database.
