http://www.thehiddenrealm.org/The Tolkienist Legendarium Elven Awakening, an E-group in which the members are in the process of re-creating the original spirituality of the Elves (or at least as close as we can) , and in particular of the "Quendi" or the Elves described in JRR Tolkien's collective Arda or Middle Earth writings, also known as the Legendarium.
