Yes, Vespera is open to affiliation :) If you would like to affiliate, just send me an email with your site address and button, and anything else you'd care to say. If you don't have a button, I'll gladly make you one! Please note that Vespera will only affiliate with Tolkien-related sites, as it feel a little silly to do elsewise!
Here are the sites which Vespera is very honoured to claim affiliation to.
Fair of Face, a shrine for Arwen's kinsman Legolas Greenleaf. A simply stunning fansite with a true wealth of information, long-running and lovingly tended. A true jewel!
Fair Lady of Rohan, a stately fansite for Éowyn, with all you'll ever need to know about the brave shieldmaiden and heart of Rohan. Treat yourself and go and visit!
Frodo Forever, the ultimate resource on the Ring-bearer himself, and being a Frodo fangirl, well, I adore it, frankly. ♥ Beautiful and informative!
