DailyStrength

An outstanding idea with the execution to match - DailyStrength.org is a social networking site designed to support people with any health issue you can think of. It's free and anonymous.

Sign up is simple and the site is well designed. They have support groups already started for just about any disease or condition you can think of from allergies to women's health. If you don't find what you are looking for, however, you have two options. You can suggest a new support group or you can start a member group and invite others to it.

I just signed up today. I'll post more after I've used it a couple times.
