Well, I'll note that DA has numerous OP-related fanclubs. Most are character-specialty, or pairing-specialty.
I noticed, although there are two different Usopp fanclubs, one for every other Strawhat, one for CP9, an inactive one for the Marine, and even ones for Helmeppo (dead) and Buggy, nobody's made any for the Arlong Pirates or indeed any of the gyojin (exception: there's one for Tom's Workers, which I assume includes him)
I was pondering setting one up.
What I had figured:
Possible Name: Fishonen (take on bishonen XD)
Possible Avatar: Cycle of headshots of the various major fishmen (help needed if I go this route– point me to clear, minimum-spoilery pics of Tom and the Foxy fishmen please so I can crop out portraits?)
If there were contests, they'd likely be seasonal/event related or theme challenges (i. e. baby fishmen), since one can't do an "birthday" contest like with the Strawhats.)
Would anyone be interested? Or have any advice? Since some of you here obviously run clubs already, advice is appreciated.
