as topic .... i would like to know, is that possible for me to bring RSS feed to my wordpress page (not blog) ?
I don't think so. The autopost feature applies only to blog entries not pages. Pages are meant to be static.
that really doesnt make sense what your asking so where do you want the rss feed to go -- like on your about page?? you can make is in the category but not page or in your sidebar
Are you talking about taking feed of products and have them insert into wordpress ? If you are, you could take the title, description, other fields and perform a sql insert statement into the wp_posts table.
