Yes I have to agree that account is definitely not a premium user. There's a difference between someone who registers and someone who has a premium account.
But while we're discussing search, I have had problems with it, not that I don't know how to use it, just that sometimes it doesn't seem to do anything. I click search, it takes a long long time to load, then the end result is a blank screen. Now this isn't the result of no search results because I know what they looks like, it just doesn't always work for me. It's possible the site was busy at the time and I got timed out but it's annoying at times.
