Serendipity Forums

I assumed that because Serendipity is not often on the approved list.
That I have to guess as to what to put in when asked for my rss feed URL. I have been putting in /serendipity/rss.php.

Is that right?
Or is there something more to this?

I just copy the link from my syndication links. I like RSS2.0, so my link looks like: http://judebert.com/wasted_youth/feeds/index.rss2

Can you just copy your syndication link?
