I'm trying to get rid of the default text on the home page. I found a post in the tutorials that said to edit the includes/languages/ENGLISH/index.php, to get rid of the "Congratulation, you have installed......" text, however the code that it says to edit on that page, in not on my index.php file. I have never edited that file, however that default text in on my site.
How can I get rid of this please?
URL is http://orchidfreak.com/store/. I am using 1.3.9h, no addons.

I would also like to know how I can add categories to the main content of the page. I don't want one box that will list all the categories (only have 3 so far), but I would like 3 separate boxes. Should i just use a table, or is there a way to do this automatically?
Thank you!
