I was kinda partial to Indelible Ink
That was pretty decent.
there were some other stories that actually went to full on complete fic that didn't turn out too badly. Just can't remember their names right now.
'No Tendo' did that... you can actually find it on FanFiction.NET. Likewise 'A Boy In The Hand', 'Laid', and 'Shared Wishes, Shared Lives', and 'Divine Blood'.
Zaxxon's stories, most but not all of the AA ones are also on FF.NET, and depending on story in partial form on other sites like MediaMiner and FicWad
Sightless Spark is a story I wish stuck to a single idea and finished it. Instead, the writer kept backpedaling and reinventing the concept. Didn't help that he'd delete whole swaths of story because he got a different idea of what to do.
For a site made specifically to allow multiple branch offs and restarts, he certainly did not use it much in that.
Actually, the only item I found in contention story wise between myself and the author in commentary was he seemed to refuse to acknowledge the conflict he set up between Ranma and the headmaster as Ranma being in the right... and the fact that the old headmaster was acting the stereotypical know it all manipulative being believing he knew all.
To be entirely honest, the version I liked most seemed to be a odd type of Familiar of Zero crossover, or in a very similar world. and the last scene had him being dragged off by the heir to the local lord to the family house to be thanked for saving the dukes daughters.
