Thanks Is there anything I should know about this forum (crazy members,especially awesome threads or nice mods or something liek that)?
Well, this forum has its fair share of characters, and they tend to make themselves apparent pretty easily. I'm sure you'll find them as you browse the threads.
As far as awesome places, I would just say to give a look to the non-One Piece sections (General Discussion, Media, etc). This forum does have a lot of interesting One Piece discussion, but there is also a lot of other good stuff as well, which unfortunately many members don't take part in.
