I second the thought that it might be Demi. She's the only LnC person I know of who wrote TNG as well. She had an Imzadi fic that I distinctly remember, so it might be her fanfic you ran into. I probably have a copy of it on my old hard drive, because I was fond of it.
But as far as contacting her...maybe one of the really, really old timers will still be in contact with her, but I haven't heard from her in years. Sorry for the bad news!
