    Howdy would you mind sharing which blog platform you’re working with?
    I’m looking to start my own blog soon but I’m having a difficult time selecting between BlogEngine/Wordpress/B2evolution and Drupal.
    The reason I ask is because your design seems different then most
    blogs and I’m looking for something unique.
    P.S Sorry for being off-topic but I had to ask!
