Disclaimer:  I have no affiliation with any of these resources other than sometimes I peruse their sites and I like what I see.  But... the internet is a fickle world and I recently went through to make sure these sites were still valid and being updated occasionally.  If you find a site that you think I should include drop me a message.  Likewise if you find any of these are defunct let me know so I can remove it and stay relevant.
