Teach me how to setup wordpress gridlocked theme

1. I notice in original theme demo, they can switch between 3 column and 2 column, I need to know how to do it. 3column: <[login to view URL]> 2column:<[login to view URL]> 2. Another thing is about excerpt, I want to limit such amount of text in home or catagory page. So I installed advanced excerpt plugin to do it, I set it up, but result still the same, all content display in home page. example: <[login to view URL]> You see the post content display in home page, advanced excerpt doesn't work for this theme! 3. I have attached a user-guide PDF, there is a part says: "The gallery format will display a slider with all the images attached to that post. To attach an image to the post, simply upload your images using the media uploader whilst creating or editing the post. Make sure you upload more than one image. If you only want to show one image, use the "Image Post Format" instead. These images will be resized to ft the theme dimensions. ? 360px x 270px - Archive pages ? 550px x unlimited - Single pages" That is a guide for a post format built in the theme, but I dont know how to use it. It says images will become a slider to display them, but if you see my home page: <[login to view URL]> There's no slider in that post. 4. I need you solve above 3 problem and report to me how you solve it. Also make my home page just like: <[login to view URL]> and <[login to view URL]> also teach me how you do it. You can login to my wordpress. ## Deliverables please download the PDF file
