Subscribe Remind will add a brief message at the bottom of each post inviting users to subscribe to your RSS feed or follow you on Twitter.
With the Subscribe-Remind plugin, some text will automatically be placed at the end of each of your posts inviting your readers to subscribe to your RSS feed or follow you on Twitter. It’s an unobtrusive and effective way to turn visitors into subscribers.
With more and more people using RSS readers to get content, it’s important that your blog’s feed be easily accessible. By increasing your syndication audience, your readers will be exposed to much more of your content.
If you open up the plugin file in a code editor, it is clearly marked where you can simply specify an alternative text.
