I am new on these LC forums but am on a sort of SCD/atkins hybrid for my IBD, and thought I'd post a few good basic SCD-related links to this comments thread:

http://breakingtheviciouscycle.info/ (start here)
http://www.scdiet.org
http://www.scdiet.com
http://www.healingcrow.com/
http://www.pecanbread.com/ (SCD for autistic kids)

There are also several current SCD-related lists but I don't have links handy anymore.
