My name is Gregory Girgenti and I am the new Babylon Babblers ' Vice President of Public Relations. I need to update our club's web site. Here is the URL to the web site - babylonbabblers.toastmastersclubs.org . How do I obtain the admin rights the site? and how do I get into the settings to update it?
