you only should add your site to pd_ring if you really offer information or downloads related to pd.
i preserve the right to remove sites totally unrelated to pd from pd_ring

becoming a member of pd_ring is quite simple:


<form action="http://pd.klingt.org/pd_ring/" method="post" target="_top">
<input type="hidden" name="base_url" value="_INSERT_THE_BASE_URL_YOU_WANT_TO_POINT_TO">
<input type="hidden" name="description" value="REPLACE_THIS_WITH_A_SHORT_DESCRIPTION_OF_YOUR_SITE">

<table width=260 height=75 cellpadding=0 cellspacing=0 border=0 bgcolor="#FFFFFF">
  <tr>
    <td width=55 height=25 align="middle">
      <input type="image" name="next" src="http://pd.klingt.org/pd_ring/next.gif" border=0 width=55 height=25 align="middle"></td>
    <td width=62 height=25 align="middle">
      <input type="image" name="list" src="http://pd.klingt.org/pd_ring/list.gif" border=0 width=62 height=25 align="middle"></td>
    <td width=63 height=25 align="middle">
      <input type="image" name="random" src="http://pd.klingt.org/pd_ring/random.gif" border=0 width=63 height=25 align="middle"></td>
    <td width=80 height=25 align="middle">
      <input type="image" name="previous" src="http://pd.klingt.org/pd_ring/previous.gif" border=0 width=80 height=25 align="middle"></td>
  </tr>
  <tr>
    <td colspan=4 width=260 height=50 align="middle">
      <a href="http://pd.klingt.org/pd_ring/info.html">
      <img src="http://pd.klingt.org/pd_ring/pd_ring.gif" border=0 width=260 height=50 align="middle"></a>
    </td>
  </tr>
</table>
</form>


alternatively you can use claudius maximus' version of pd_ring that validates with the W3C (X)HTML and CSS validators.:

if it turns out that the idea of giving everybody the possibility, to add his/her site to pd_ring, without a checking of the content, was too naive, the procedure of becoming a member might be replaced by some kind of passworded system in a future release.
