All known bugs and errors are posted here, so keep this in mind before implementing the script.

• Can't post comments on Wordpress-websites. If you want to use this in a Wordpress-theme, you'll need to add the denyFormRule for wp-comments-post.html
  bda.denyFormRules.push('action.contains("wp-comments-post.html")');This seems to be fixed in Wordpress 2.6 ?
• Javascript included in pages that are loaded using AJAX will be discarded. Use the addEventListener-function on the load_complete event to execute javascript onload.
• Your visitor tracking system will register a link as "http://www.bydust.com/#/implementation.html" to the main page instead of to implementation.html, which is the page the user requested. The user will be redirected to the right page however. You can retrieve the current page URL through bda.currentHistoryLocation, which returns a String. Thanks to Fahed for mentioning.

Thats all !
