Can someone change the title of a forum thread for me?

Some time back I changed the title of one of my town threads (http://www.ecocitycraft.com/forum/threads/erebor-town-thread-sale-now-on.47203/) but I did not realise that after a certain amount of time it cannot be changed back. I need the 'SALE NOW ON' removed from the title so it's just 'Erebor - town thread'

Thanks
