IotaNet,
I have to agree w/ Hootie, your website is truly awesome! It has A LOT of info on it as it is. But being that I am the National Webmistress for my young sorority, I know how you feel about wanting to make sure interests have all the info they need about the org. I am actually in the process of doing our National site as well. One thing I can suggest to you that I am putting on our site is a message board/chat room. Both of these methods will allow interests to ask any questions they have about Iota that all brothers can answer.
Another thing you can add is a brother testimonial page. That way, interests can get a more intimate view of how brothers feel about the fraternity. If you decide to do this, maybe you could email brothers w/ a list of questions they could answer for the testimonial (i.e.-what have you gained from being a brother? what attracted you to Iota? what is some advice you can give a man interested in Iota? etc, etc). You can have brothers answer 1-2 questions from the list.
Those are just some things I can think of off the top of my head. But I think your page is great! Keep up the great work!
