A tip:-

I noticed we can easily link it with Google webmasters account so that we do not need to submit it their manually everytime.

1. First make sure you're .htaccess is working fine and sitemaps are generated.

2. Simply sign to Google Webmasters -> Dashboard -> Sitemaps -> Add General Web Sitemap -> and give your sitemap URL as http://www.yoursite.com/forum/sitemap_index.xml.gz and Add it.

This way your sitemap would automatically be updated.

3. You can do the same thing with Yahoo Site Explorer.

Go to Yahoo Site Explorer -> My Sites -> Manage -> and Add Website Feed as http://www.yoursite.com/forum/sitemap_index.xml.gz

Yahoo doesn't update/download sitemap automatically, so all you need to do is to Select your feed and click "Resubmit".
