  1. Hey there! I know this is kind of off topic but I was wondering which blog platform are you using for this website? I’m getting fed up of WordPress because I’ve had problems with hackers and I’m looking at options for another platform. I would be awesome if you could point me in the direction of a good platform.

  2. I truly love your site.. Great colors & theme. Did you develop this site yourself? Please reply back as I’m attempting to create my own personal site and would like to find out where you got this from or just what the theme is named. Thanks!

  4. I’m really enjoying the theme/design of your site. Do you ever run into any browser compatibility problems? A small number of my blog visitors have complained about my site not operating correctly in Explorer but looks great in Chrome. Do you have any tips to help fix this problem?

  5. Wow that was odd. I just wrote an extremely long comment but after I clicked submit my comment didn’t show up. Grrrr… well I’m not writing all that over again. Anyhow, just wanted to say fantastic blog!

Hey I am so excited I found your site, I really found you by accident, while I was researching on Bing for something else, Anyhow I am here now and would just like to say thank you for a incredible post and a all round thrilling blog (I also love the theme/design), I don’t have time to read it all at the minute but I have saved it and also included your RSS feeds, so when I have time I will be back to read a lot more, Please do keep up the fantastic work.|
