  3. I know this if off topic but I’m looking into starting my own weblog and was wondering
    what all is required to get set up? I’m assuming having a blog like
    yours would cost a pretty penny? I’m not very web smart so I’m not 100% positive.
    Any suggestions or advice would be greatly appreciated.

    Thank you

  4. Hi, There’s no doubt that your website may be having browser compatibility issues.
    Whenever I look at your site in Safari, it looks fine however, if
    opening in IE, it’s got some overlapping issues.
    I just wanted to give you a quick heads up! Besides that, great site!
