I don't seem to find the way to get the coupon code so is it visible once user have registered?
It seems the coupon is visible via the coupon's block title. It says coupon: couponcodehere
I find the site to be very pleasing to the eyes! The design is nice and smooth. I did try to click on the logo to go back to the home page, but it was not clickable. Many people are used to being able to do that, so it might be beneficial to link the logo to the home page
This site will do great for domain and hosting coupons, and it will do great for online stores as well! I see you have a section for stores, but you should really see if you can find more coupons for more online stores!
I dunno what the user control panel is like, cause you did not offer a temp login for us to use. We do not create registrations to test and review that part of the site, but if you create a demo account then we can review the user control panel and test it out.
You need to see about using clean URLs instead of the ?sid=2 ones. This will help you out with SEO and to be honest ... I am a big hater of showing your code in your URL.
More articles will be great too!
The user profile seems bland and lacking. There is space that can be used on that page. Maybe allow the user to tell more about himself, and maybe an avatar? Turning it social would be great too! Allowing users to friend other users that they like and believe offer great coupons.
On that note, you could even offer RSS feeds of user coupons so people can follow new coupons from other users. Also, a main RSS feed and an RSS feed for each category.
Hope this review helps some
Oh, xhtml validates, but CSS has one error.
