I landed on ranma.de some time ago and immediately started to rummage through the archive.
However, many of the FF stories were not finished and the updates were already a while back, so I wrote a PM to the respective authors (if a farewell had not already been written down)
I gradually found the pages where they settled:
most of all they are on

www.fanfiction.net

to find.
Even on sites that are not yet as well known as

www.fanfiktion.de

there are some nice stories to be found.
English skills are on

www.mediaminer.org

to recommend. Most of the FFs there are in English, but absolutely worth reading.

I recommend everyone, whether they are DB / Z / GT, Yu-Gi-Oh, Ranma or whatever readers and writers, to visit these pages.
