I stink at this blogging stuff!

Ok so I was told to get some posts on here pronto but I honestly don't know what I'm doing or how I have gotten this far. I'm not the most computer literate person ever that's for sure. So here goes nothin! I'm kinda figuring it out but not really. I don't know how to make my posts smaller and many other things. So anybody feel free to give me some pointers!
