Hi Bitten,
Three other sites that come to mind are the sister site to this one:
lcfanfic,
the fan fiction web site, and one I am pretty new to:
Archive of Our Own. The first one is dedicated entirely to Lois & Clark. The other two have a large variety of fanfic, only some of which is based on L&C.
Are you interested in Superman more generally or just L&C? An excellent resource for all things Superman is
the Superman home page.
I hope this helps.
Be well,
Lynn
