I want to add RSS ability in my web site([login to view URL]) If it is possible add it for me( I want to have RSS for products ) ( RSS is a file with XML format for last updates in prices or adding new products) I want to have RSS in my web site exactly like [login to view URL] forms ([login to view URL]) first shows Rss in homepage with some most important products then in RSS page shows all the products. The information for each product(in subject part) should enclude with 1.price-brand,s name [login to view URL](is it possible to add date in shamsi format-Iranian format?) Could you add also something to sign or mark the last added products. And a sign for Top 10 products (in sale or search) the important point is that i don,t want the sign or mark for the last added products and a sign for Top 10 products in RSS, I want ot have it in whole of pages for all of the options and products(this part is not included in RSS part).
