I have used GSiteCrawler before with good results.

Personally, I like a more hands-on approach - where I can control what urls are listed in the sitemap, what order they are listed in, etc.

For those who are more DIY inclined here's another option that may be useful.

You'll need:

1.  A browser window open to the Free ROR Sitemap Generator - http://www.dlperry.com/ror_sitemap_generator.html

2.  A free copy of the RSS XML Sitemap Template - http://www.dlperry.com/rss_web_feeds.ht … apTemplate

3.  A plain Ascii text editor.

Run the ROR Sitemap Generator for your url
Copy the resulting data, and Paste in a New file in your favorite Ascii text editor.

In the same text editor - open and save a copy of your Sitemap Template - renaming this file to whatever your sitemap filename will be (usually sitemap.xml, but it can be anything.xml)

Then just copy-n-paste the appropriate data from the ROR file to the xml Sitemap file, and save.
