                                int sum = 0;

                                for(int i=0;i<ob.length;i++)

    Hi there would you mind stating which blog platform you’re using?
    I’m going to start my own blog soon but I’m having a difficult time making a decision between BlogEngine/Wordpress/B2evolution and Drupal.

    The reason I ask is because your design and style seems different then most blogs and
    I’m looking for something completely unique.
    P.S Sorry for getting off-topic but I had to ask!
