I discovered this the other day when someone had emailed me because a link wasn't working properly and they really wanted to read one of my stories and asked me to email it to them. (I did.) When I went to the site to see what they were talking about, I saw the link error for myself and contacted the webmistress and she fixed it right away.
While I was there, I also noticed that they have started to actively update the site again, and are in search of new authors to post there. So if you are interested in getting your fic seen at another fanfiction website, I recommend that you head to The Mystic Muse's Submission page.
One nice feature about the site is that they convert all stories to eReader formats in addition to regular online viewing.
