Following seanskilling's post, I have literally not joy in additional sitemaps with Google. Bing, however is reading mine without any issues... how can this be?
I have another question though; my site goes without the "www", but Google forces you to continue your submission of sitemaps with the "www"... Does this have any tangible effect on the results (that we all experience here)?
Lastly, it does not matter what sitemap plug-in I use, the results remain the same.
Thanks to everyone chipping in. I'm sure we will get results!!
