I used to support Mamoru and Usagi when I first started watching anime. (but I used the dreaded english names, ugh.)
Also, really used to support advanceshipping, but that's just kind of died out. MangaQuestShipping is one too, but now I ship Crystal with Silver instead. :P
Gosh, it's really hard to think of shippings I used to support, but now don't.
