I think Circle Dance is from Taterville? If you have specific stories you want I'll have better luck searching my folders. https://mega.nz/#!8OA1yLoY!n1EIRYfr4oPK0mMbD6NqJBFnyFo52P3vZU5fvgVlrew
Have you tried archive.org? https://web.archive.org/web/20160205065219/http://www.amethyst-night.com/refuge/index.php lists a lot of old HL fic and might be a place to start.
https://web.archive.org/web/20130203051003/http://www.taterville.com/listings.htm is a list of all the Taterville fic, and though it won't link to any of them it gives you authors and titles to start searching in case any of them have gone up elsewhere.
