Used the original version and there was an option along the lines of 'Generate a sitemap now' which I cant find in the MU version.
There is a 'Search engines haven't been notified yet. Write a post to let them know about your sitemap.' However my site is a news aggregation site so doesn't have any posts or comments (and never will). Just has pages full of widgets.
Is there a way to kick the sitemap generation and notify the search engines?
Thanks
Mark
