  1. Howdy! I know this is somewhat off topic but I was wondering which blog platform are you using for this site? I’m getting fed up of Wordpress because I’ve had issues with hackers and I’m looking at options for another platform. I would be great if you could point me in the direction of a good platform.

  2. This is really interesting, You’re a very skilled blogger. I’ve joined your rss feed and look forward to seeking more of your excellent post. Also, I’ve shared your website in my social networks!
