[Plugin: Google XML Sitemaps] XML Sitemap Generator for WordPress 3.2.5 does not notify Yahoo

The company that installed XML Sitemap Generator for WordPress 3.2.5 evidently chose not to include Yahoo as someone to notify and or authorize access to the Sitemap. Yahoo is NOT notified of changes. Google is. Bing is, and Ask.com is. But not Yahoo. How can I include Yahoo? Yahoo does NOT rank my site. Google and Bing do!

Note the company that installed 3.2.5 on my WP site and built the site is no longer in business.

PS to Arne. I doubt the company that downloaded 3.2.5 sent you any money. I believe in doing so, but I will not use PayPal for security reasons. Is there any other way you can accept donations?
