Oops, I forgot a few.
There is a fansub list, which is for trading fansubs of anime.
The list for DNR, (Ranma in college?) sort of a fanfic list for just one
series. This has not been very active recently, but it is worth joing if
you like the series. (IF you are unfamilar with DNR, it is one of Mr.
Biles many pieces fiction. I think it retains the original spirit of
Ranma better than any other fic out there.)
The ACO (Anime Club Officers) ML. The name says it all.
Again, if you want instructions for joining any of the lists, send me a
message to let me know.
