Help Developing RSS 2.0 feed

Hi -

I'm trying to learn to write this xml file so I have a 2.0 RSS feed to mesh with TwitterFeed and their new interface.

So I'm almost there and having problems. -- I send the feed through FeedValidator.org and the results are below. My questions are:

1. how do I fix the problems

2. Is there a way to automatically rotate the pubdate so that I'm not doing it manually every day? Just seems that it shouldn't be necessary to do it manually. I have the feed to the whole blog and not to a specific page or post. I have to have a pubdate for Twitter Feed to read that changes every 24 hours - or a GUID element - which again would have to rotate and be different for each post.

3. Should I be doing something else to develop an RSS 2.0 feed - cause as you can tell I DO NOT know what I'm talking about!

THANKS in advance!

Gail

This feed does not validate.

In addition, interoperability with the widest range of feed readers could be improved by implementing the following recommendation.
