There has been a vast amount of help on Deviant Art and support from everyone for Japan in the time after the tsunami hit. Though we here at Travii's Army are not speficially doing anything, I will urge you to look at the charities and foundations that have been set up around the site and to help out as much as you can.
If you don't know where to look, head over to Moonbeam13
's page. There is much to do there.
