You might want to check out a few things that I found on your site.

In your creed, the word "gentleman" seems like it should read "gentlemEn.
Also, your manuals are for sale online, via CafePress. Anyone can just buy the materials instead of following your chartering process. You might want to change that.
You might want to explain a little further (on your site) how/why you are the fraternity "of the future". It seems like you are offering a "fraternity in a box", yet steering away from any governing body or HQ. Just be aware that if several groups with the same name are opering differently, with different tax liabilities and legal designations, you might run into some problems.
Under "Recruitment", it reads
"Sitting alone in your room doesn’t lead to many lasting memories of college. There are a variety of social activities that fraternity men become involved in. Intramural sports are a fun part of the fraternity experience. Whatever your skill, whatever your interest, there is a team for you to participate on."
Does this mean that your fraternity is about intramural sports?
These are just a few things that came to mind when I checked out your site. Good luck in your endeavours.
