Warning:  This site is for the serious survivor.  The cadre here is the real deal.  Those with a penchant for braggadocio need not apply.  This group has "been there and done that" and though they are willing to pass on their knowledge to those who are sincere in their quest for survival skills, they will spot a "wanna be" from 3 clicks out. 
A site dedicated to self-reliant living.  If you join their forum, you'll be expected to "grab an oar and start rowing".
This is a great site for learning your knots.  Knowledge of knot tying in regard to survivability is a must.  Highly recommended. 
An interesting site that can give you some great ways to bring extra cordage with you wherever you go.  The rule of thumb to remember for survival is "you can never have too much cordage".
