Very nice and I appreciate you including lefties. If I could suggest anything it would be maybe consolidating the navigation a bit. I don't mind clicking around but there's a lot to digest.
Yep you're right. The fact is that the content on the website has grown a lot in the last years, there's really plenty of information. I try to help users digest the material with an autoresponder that starts when users subscribe; they receive periodic email with step-by-step chunks of information. Thank you for your feedback!
