[thelist] rss help - dynamic urls

[Chris Ditty]

Hi all.  I am trying to offer my users a rss feed.  I found a nice
litle script that does most of my needs and I have it mostly finished.
 I just tried using the link tag with a dynamic url and it turns out
this is being tagged as invalid.  Out of curiousity, I looked at
yahoo's rss feed and I see that they are using dynamic urls.

Can anyone offer any suggestions as to how they are doing this?  I am
running rss v2.0.

I noticed that they are using a * as a seperator and then give the
sendto url.  I want to use a simple id tag and send them to a given
url that I can change if needed.

Can anyone think of a solution for this?

Thanks 
Chris
