Every wordpress blog has an RSS feed for comments and for posts (entries). This is the URL for the feed for your blog’s posts (entries):
http://sarchitecture.wordpress.com/feed/ If your website has the ability to draw from an RSS feed that's all you need.
If it doesn't know that we do not provide support for installing the capacity on your website to draw the RSS feed from your blog.
Support for your website software and any advice you need are provided on the WordPress.org support forums and they are here http://wordpress.org/support/ If you don't have a username account at WordPress.org, click that link and register one on the top right hand corner of the page that opens, so you can post to the correct support forums for your software.
