This is a reasonable list that is comprised of several other lists and de-duped, etc.

+1 Skullsecurity has some good lists.

My first pick would also be Skull Security.  I'd also recommend:

If you're using JTR, I suggest you check out (if you don't know already) the --mangle option.
You probably already know this but I'll throw it out there... You could also make your own wordlist after gathering info, email addresses, names.  The company's password policy will give you alot of helpful information minimum password length, complexity, how often it changes, etc.

Have fun! :-)

I have been assembling one of my own from other small wordlists to create one massive one.  inreagrds to the JTR mangled syntax.

Once I have the wordlist  how am I supposed to assemble the syntax so it uses the wordlist and then rearranges the words. 

I've seen this syntax so far but not many others:

john --rules --wordlist=mangled.lst all.lst  shadow

Will that work?

The single largest worldist that I have found is purehate's wordlist. 2.5GB. Word of warning, make sure you have a beefy system before you try to use it.

The other 1 I remember was called GDict, but I dont remember where I found it.

Joshsevo- sounds like you may have to bruteforce it. I would suggest Amazon Web Services if you have to go that route (http://www.securitytube.net/video/1984).

I've been working on some of my own specific, broken down word lists.  These are really designed for brute force questions, such as "what was your first pets name" or "where did you go to school"... feel free to have at them...
