<p>This plugin represents a RSS feed separator, which enables your readers to create RSS subscriptions that only contain posts with specific tags.<br />
For example, visitor A could create and subscribe to an RSS feed including the tags <em>cooking</em>, <em>recipes</em>, and <em>fine living</em>. Visitor B, could<br />
instead prefer to read posts related to the tags <em>cocktails</em>, <em>wine</em>, and <em>night life</em>. Each person will have it’s own RSS Feed URL, and each of<br />
those feeds will only include posts that have one or more of the preselected tags.</p>
<p>If you have a busy blog with lots of entries in it, you should definitely consider installing Selected Tags RSS, in order to enable your visitors<br />
to subscribe just to the topics they are interested in.</p>
<p>You can configure the location where the the RSS selector would be showing from the plugin settings. If your theme supports widgets you can add and configure a widget from <em>Appearance > Widgets > Selected Tags RSS</em>.</p>
<p>The plugin supports shortcodes. Use <code>[selected-tags-rss-post title="***"]</code> shortcode to show RSS link in posts and <code>[selected-tags-rss-search title="***"]</code> to show the RSS Selector. Title parameter is the optional name of link.</p>
