re. www.simsinteractive.com/index.htm. This page had been indexed and
appeared last week in Google listings but has now disappeared, but the
root URL is still present.  Is this because I changed the content of
the page just before the last spider? or could someone else be flagging my site
as spam by over-submitting my site to the Google database?

It is not possible to over submit your site. Your minimal listing on
Google suggests that other sites link to yours, but they were unable
to index any content. Re-submit your site (use this URL:
http://www.simsinteractive.com/sitemap.htm ), and wait until the next
update.
