Thanks all for the excellent suggestion!
I'm grateful for your time but first, I need to apologize because I realized the first widget at the sidebar also appear deeper in the category pages and logout page. In other word, I couldn't just target only the first widget at the homepage, it was wrong approach. In such case, what do you suggest? Or what is the best way to do this?
So sorry for the wrong information as I'm still trying to familiarize with this new directory theme.
Many thanks in advance again.
