LUMOS charity was co-founded by JK Rowling www.lumos.org.uk/
Go here for details about this money raising campaign: purpelblur.deviantart.com/jour…?
Basically, for everyone who changes their avatar to one of the HP spanking icons made by Zani-Loki, PurpelBlur will donate 10 cents to LUMOS, the charity. All you have to do is change your avatar to one of those (all posted here: zani-alone.deviantart.com/jour… ) and then comment on the journal entry here: purpelblur.deviantart.com/jour…? , and wait for PurpelBlur's reply. Once you receive the reply, you can change your avatar back. Cool, right?
