As soulseeker said, the lore section
of the official forums is a good place. Specifically, I would recommend checking out the lore FAQ
there, which contains many answers to many questions, as well as many useful links.
It all leads somewhere, though. Two words; Imperial Library
, The. IMO, the best source of TES lore and good reads in general about TES related things.
And one of our administrators here, Sinder Velvin, is a librarian there. I'm sure he could offer you a great deal more and better guidance than I could.
If by website you mean the waiting4oblivion site, go ahead and ask the administrators (I could forward a request if you wish)!
Other than that, we have, as you've seen already, the Fan Fiction
section and the TES F'Ruum
community mod section, all worth checking out and interested in your writings and editing assistance, I'm sure. You could perhaps speak to minque
about editing assistance (your name in the sticky, maybe), and Troika
if you're interested in writing or editing for the TES F'Ruum works.
Just speaking my mind of suggestions, of course. Have fun now.
