Upgrade Notice : 
If you have a previos version downloaded from my server (www.cuvintealese.ro), after update you may notice that now you have 2 versions of the plugin, one updated (ver. 0.5 ), and one still not updated (ver. 0.1 ).If so, just delete the not updated version.No loss whatsoever.The inconvenient comes from a mistaken “underscore” which was suposed to be a hyphen, so wordpress won’t recognize that folder on update.
The plugin shows below each post the name (link or text) of the people who visited it, based on their cookies, and their comment status approval.The plugin is a win-win model type, on one hand – for all the times when the user doesn’t feel or doesn’t have anything to comment, but he still marks his visits on your blog, and on the other hand – he gets “repaid” for his visit by listing his name under the posts he visited.
The plugin list the visitors name based on their cookies, if no cookies then a submit form will show up. 
For preventing spam, displaying the visitor’s name will need at least one comment approved. 
You can setup the plugin to show the name as link(if any) or text

Visitors Notify

When your visitors don't want or don't have anything to comment, they can still mark their visits.

What Would Seth Godin Do lets you greet first-time visitors with a tailored welcome message — like an invitation to subscribe to your RSS feed — and show a different (or no) message to people who have already been to your site before.
The plugin stores a small cookie that counts how many times a visitor has been to your site. While the count is at or below the “# of Repetitions” threshold you configure, the new visitor message is shown. Once the visitor exceeds that threshold, the return visitor message appears instead.
Inspired by Seth Godin’s 2006 blog post: <a href="https://seths.blog/2006/08/in_the_middle_s/" rel="nofollow ugc">…in the middle, Starting</a>.
Features:
<ul>
<li>Separate, fully customisable messages for new and returning visitors.</li>
<li>Configurable repetition threshold — choose how many visits count as “new”.</li>
<li>Choose whether messages appear before or after post content, or only where you place the <code><?php wwsgd_the_message(); ?></code> template tag.</li>
<li>Option to show or hide messages on Pages (vs. Posts only).</li>
<li>Exclude specific post or page IDs from showing any message.</li>
<li>No external dependencies; lightweight vanilla JavaScript.</li>
</ul>
