  12. Hey there just wanted to give you a quick heads up. The text in your post seem to be running off the screen in Internet explorer. I’m not sure if this is a format issue or something to do with internet browser compatibility but I figured I’d post to let you know. The design and style look great though! Hope you get the issue fixed soon. Thanks
