Here's some criticism (I hope constructive
* Why do you have both Name and Username? I've entered exactly the same into both, so why not merge them?
* Why do I have to supply my name and email when posting an experience if I am already logged in?
* Also, the whole process of submitting experiences is wrong in my opinion. You should look into sites that already do such things as customer feedback and take ideas from them.
In my opinion, people should just be able to post negative or positive comments about a service and a rating...
