You can read about the charity here. If you would like to help raise awareness on LiveJournal, upload a new usericon using this URL and use it as your default usericon at least temporarily. You can also link to this post using this URL if you want to. And please, please post a comment if you've helped raise awareness or even donated to the cause. The more LJ-using peeps that can help out, the better. Thank you!
