Mnemi (aka Celeritas) is a fan-fiction writing queen of lurkdom who prefers a non-androgynous nickname, likes British spellings, loves the Shire, and seems to choose to give the impression of being the alter ego of somebody or other and/or a duck.
She feels fan-fiction too often puts the fanauthor's intentions above those of Tolkien, referring to this as "magisterial" as opposed to "ministerial" fan fiction (the latter being that which keeps to Tolkien's vision). From her blog, she seems to be a very articulate and innovative thinker who will certainly be an asset to the Downs. now that she is among the actively posting dead.
