become a member pd

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:

all you have to do is to include the code below in your page(s) and replace the values of the hidden fields

for https sites please replace all occurences of "http" with "https"
please do not insert blanks or line breaks between <input type="image"... and </td>
otherwise some browsers like IE don't show the table correct
insert a base_url if you want to jump people to a specific html page on your site. eg if you hostname is pd.my-site.net and you want http://pd.my-site.net/pd_index.html as entry for users of the ring, the base_url field should be /pd_index.html the base_url should contain the pd_ring form,otherwise "ring surfers" will get stuck.
insert a short description like a documentation project plus a download-site for patches
both, base_url and description can be left blank if there's nothing to say
the hidden fields should be the same for all (html-)pages on your site
the .gif images included in the form are transparent.
if you want to you can replace the background color of the whole table with some color more apropriate for your site.
if you want to, you can download the included .gif images to your site and include them locally.
in this case the <input type="image" would have a src="http://pd.my-site.net/images/next.gif or similar
to update the information later, you just have to update the hidden values
if there is no user visiting from your site for more than one month,
the site will be excluded from the list, to prevent linking to dead sites.

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.
