Terrible tragedy has struck Japan; the earthquake, the tsunami, and now facing issues with nuclear reactors, it all can be a bit overwhelming. So how can you help? Very easy you can either click this link http://www.huffingtonpost.com/2011/03/11/how-to-help-japan-earthquake-relief_n_834484.html
Or if reading a page of text doesn't appeal to you and you just want to text something:
REDCROSS to 90999 donates $10 from your phone to the RedCross
MED to 80888 donates $10 to the International Medical Corps
There are many worthy organizations that need help helping Japan (was that a grammatical nightmare sentence or what?), and we aren't the ones to tell you how to help. Find a cause that you think is best, just do us a favor and find one. Anything you can give will help someone.
