Incognito, after the show ended, a number of authors wrote a season five and a season six for Lois and Clark. That was how I first started reading Lois and Clark fanfic. You can find these stories here:
Season Five and Six Stories (Hope the link works. I've never posted a link before
)
Anyway, it was a great starting point for me. Followed by reading Kerth winners (mentioned above)
