<h1>how to join the webring</h1>
|
|
|
|
<p>This webring can be joined by any user on tilde.team.</p>
|
|
<p>First, add the following code 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>see webring source <a href="index.php.txt">here</a></p>
|
|
<p>it will probably work if you copy it to your <code>~/public_html</code></p>
