  2. Hello would you mind letting me know which webhost you’re using? I’ve
    loaded your blog in 3 completely different internet browsers and
    I must say this blog loads a lot quicker then most.
    Can you suggest a good internet hosting provider at a fair price?
    Thank you, I appreciate it!
