    <content:encoded><![CDATA[<p>I was able to get the Look up ready to flick BBG back on line,  How you like my design? It currently matches my account at <a href=“http://www.myspace.com/nightvixen” title=“nightvixen@myspace”>myspace</a> and it blends with my LiveJournal; <lj user=“Nightvixen”>, I made my header girl in Poser6, Using Victoria with <a href=“http://market.renderosity.com/mod/bcs/index.php?ViewProduct=35684” title=“Shapes: Kielo”>Kielo</a> and the <a href=“http://market.renderosity.com/mod/bcs/index.php?ViewProduct=41941” title=“Young Soul: Fragola”>Fragola</a> clothing with <a href=“http://market.renderosity.com/mod/bcs/index.php?ViewProduct=32771” title=“Sterling”>Sterling</a>. It took a While to get what I exactly wanted but I did get it!

<center><b>Above:</b> Rest in Peace my Friend; Joe whom was better known as <lj user=“Jerris_darkrun_”></center>
</p>
<p>
I had been having a disagreement with my partner on the phone on the 8th of Feb 2006 when I got off And came outto the Living room my Mother asked if I knew Of Jerris_Darkrun_, I replied I did and Then she told me, He was dead. Founding

I’ve got a similar problem and my XML atom feed does not validate at all. Getting errors like this: “This feed is using an obsolete namespace used by an obsolete snapshot of Atom, which is not supported by this validator.”

No one seems to be very forthcoming on how to fix the RSS problem “content: encoded” or my xml problem.

Would appreicate some help here.
