With Smartfeed you can create your own personalized newsfeed from posts on this board and read them with the newsreader of your choice. Smartfeed supports authentication for registered members, allowing them to view posts in forums that others may not be able to read.
Smartfeed also supports a topic feed. You need to know the topic number to use this option and it can be used only for a single topic. The easiest way to get a feed URL for a particular topic is to view the page source when on the topic page of interest. You will find the URL in the markup in a <link> tag. It will look something like this: /app.php/smartfeed/feed?tf=123. Copy that link into your newsreader.
