At first glance, your website is very captivating and I like the fact users will know exactly what the purpose of the website is the moment they visit the site. I did notice some minor typing/grammatical errors in the introduction, so you might want to fix those.
The topics on which you have chosen to focus are good in that they are not too specific or broad. Obviously you have some material to add to the various pages of your site. I'd like to see how you're going to utilize the graphics you have already placed on your site to teach about inserting graphs, columns, and tables.
I like the layout/theme of your page. It definitely fits it purpose. I am looking forward to seeing how you tie the graphics into a tutorial for the users. I think that being able to visualize what you are suppossed to be doing it a huge help to people who are struggling with a new concept. I am excited to see how it all ends up.
