Name your favourite posters in HJU, compliment them or do whatever you like .... for me, well i'd say Raida123 because most of his post can be funny at times ...
MaskedShuuyu (did you honestly think I wouldn't put you?), Ryoutarou (my favourite sempai), Keith Justice (I'm just sayin'), Faded.Memories (you can be so cute sometimes!), Bolt (his posts annoy me most of the time but I find them rather amusing) and of course my EJF colleages, Takuya, Shadow Falcon (or is it Phalaon or ...?), Inui Takumi, Kagami Arata and toranoko.
EDIT: I almost forgot Igadevil's wisdom and dukemon22's rumor threads.
Keith (of course), kC, Vash, Hariken, Fayt, Merk, Ayumi, JFC, Mika, Yellowstranger [from irc chat, he doesn't post here much].
See, now I feel guilty if I forget about someone I really like, and then they get upset that I didn't mention them, and then I say, " But I meant to put you, I just forgot!" and then they're like, " Yeah, whatevs."
