You answered your questions, you gave it a sitemap with invalid URLs ...

I see that and I understand the invalid URL's but, I was expecting someone to actually view my site and tell me what I did wrong so I can fix them. They all work. The fourth error is not a link I created, it is a link defaulted by the Template. I am very new to this but, I am very suprised that's all the errors I had.
The Google Webmaster site also said that some URL's might have errors and may not be fixed.

Copy the URL - it doesnt work (404 error - ie cannot be nfound)

Your forum doesnt need a site map.

I don't need a sitemap to be searched in Google?
I tried to Google my site before submitting the sitemap and could not find it.
