Community Support Appreciated

Hello, I've recently put online a website that I've been building for the past couple of years.

It is a new approach to online intelligence tests, you can view and participate at my-iiq.isdigital.com
I've had the site up for a couple of weeks now and I am getting valuable feedback from other forum communities.

I'm interested in advice that will allow me to tackle the shortcomings of the website with a more cohesive approach relating to the different languages I've used to develop it. This will mean following through with the experience the website has to offer.

I'm looking forward to the constructive criticisms.

I tried several times but your site isn't loading, even the server is not responding to a ping request.

try mywebsite.isdigital.com/App/Main.aspx
It does take some people a really long time to connect. I've heard upwards of a minute in extreme cases, which i know i terrible. It is one of the biggest pressing issues involving my site. One which is severly cutting off much need feedback.

I couldn't connect.
