Respectful Comments is a Wordperss plugin that changes the text of the Submit Comment button to My comment respects the blog and its readers.
Readers that want to comment in your blog will:
<ol>
<li>Read your expectation from them in a one line, easy to understand text</li>
<li>Will not skip reading what you expect from them.</li>
<li>Will not need to click “I have read the terms…”.</li>
</ol>
My comment respects the blog and its readers is the default text that this plugin comes with. You can change the text to anything you wish, in any language.
