I was reading MuggleNet.com today when I read about Seabottom/WB/whatever registering the domain name harrypotterandthehalfbloodprince.com. I thought I would look up domains of the format harrypotterandthewhatever.com and see if any had not really been picked up by the Potter websites out there.
I found a few that hadn’t. I determined this by a quick search of Google, so I may be wrong. Anyway, here they are.
For confirmation, go to register.com and use the whois lookup tool.
Harry Potter and the Curse of the Dementor
Harry Potter and the Deathshead Plot
Harry Potter and the Hogwarts Shallows (similar to Shallows of Hogwarts, of course, but not the same)
Harry Potter and the Serpents Revenge
Harry Potter and the Tower of Shadows
You never know, of course, but chances are none of these titles will be used, so it just makes for good fodder. :)
