<p>this webring can be joined by any user on tilde.team.</p>
|

<p>first, add the following links to your page, replacing USERNAME by your username (no ~):</p>
|
|
|
|
<pre><?=htmlspecialchars($snippet)?></pre>
|
|
|
|
<p>you may edit the code however you want. it should work as long as the URLs are kept in place and have your user in them.</p>
|
|
|
|
<p>then create a .ring file in your ~ to be added in the webring:</p>
|
|
<pre>$ touch ~/.ring</pre>
|
|
|
|
<p>the first line of ~/.ring will be displayed here as a tagline.</p>
|
|
<p>the second line of the file is used as a custom link if your webring tags are not on your homepage.</p>
|
|
|
|
<h3 id="explore">explore webring</h3>
|
|
<p><a href="?action=random">jump to random page</a></p>
|

|

<ul>

<?php foreach ($users as $user):

</ul>
|
|
|

<p>it will probably work if you copy it to your own <code>~/public_html</code> and adjust the links accordingly.</p>
