I don't remember that ever being discussed.
I remember we voted to change the old Hamtaro logo to the Haruhi one years ago, but if there have been plans to change it again then I've obviously missed out on the discussion.
I can see the sense in changing it now though. Since after the forum upgrade the soc logos have all been stretched to 100x100, and our current one doesn't look that great. I'd be happy to put it up for a vote like last time, so if anyone has any suggestions then by all means post them here.
