Hmm, some people on this forum cant take other people's opinions as an answer, they think there opinions are good and everyone elses are not right!
Virdox (Also known as Virdox) created the layout, however it does look similar to the work of another designer. It isn't ripped, I was there when that site was being developed - its new and unique to that website.
The site was sold as-is to the current owners from Virdox for £60 or something, I believe? With everything in it.
You were sold it with the content unfinished, so its a bit of a bummer that you didn't complete the final pages - it would have given the site that much more, it has the potential to go far.
