There are many excellent websites, both about Paganism and about self-injury, and these are my favourites. Suggestions are welcome.
Secret Shame the daddy of the self-injury websites, this is professional, and highly informative. If you read no other SI website, read this one.
The Lysamena Project on Self-Injury this is a Christian site about self-injury, with some good information and the like. The only other site which addresses SI from a religious viewpoint (and indirectly the inspiration for this site), it is definitely worth a link even if some of the information is not too useful for Pagan SI-ers.
Self-Injury: A Struggle a website containing personal writings of people who self-injure, their thoughts, poems, artwork, etc. Also a large quotes section with quotes applicable to SI.
Safe Haven the large, active message board from the above site.
Recover your Life the new home of RuinYourLife, this site has information, lyrics, poetry, a message board etc for SIers and related issues.
SIARI (Self-Injury and Related Issues) British site with information, words from sufferers and news.
Self Injury Support aims to be a non-triggering site, and has a list of referrals.
Blood Red information and ideas for how to stop SIing.

Self Injury Abuse Trauma Directory just what it says on the tin, this site provides links all over the web.
SAFE (Self Abuse Finally Ends) is an American organisation treating SI and which has a treatment centre.
LifeSigns a British self-injury organisation which aims to promote awareness of SI. I am a member of this one, I think.
Young Minds Offers booklets on mental health information (including SI) for young people.
A Gentle Touch not strictly for self-injury, but a whole host of related issues including incest, rape, depression and others, it also has an excellent links section with links to all kinds of things.
