“Mention comment’s authors” is a plugin that improves the WordPress comments fonctionality, adding a response system between authors. 
When adding a comment, your readers can directly mentioning the author of another comment, like facebook or twitter do,using the “@” symbol.
This mention plugin add two features :
<ul>
<li>In the comments field, when an user entered the “@” symbol, it allows, through an autocompletion system, to quote (or poke) a preceding commentator.</li>
<li>Once comments validated, the mentioned names take the appearance of buttons. When the user clicks on it, window scrolls to the preceding comment from the person named. A class is added to it, for temporarily customize it in CSS.</li>
</ul>
This WordPress plugin is based on <a href="https://github.com/tactivos/jquery-sew" rel="nofollow ugc">“jquery-sew” jQuery plugin</a>, by <a href="https://mural.ly/" rel="nofollow ugc">mural.ly</a>.
