I am guessing you are referring to the club's home page, which has content dating back to 2016 (!) The content would be modified by the administrator or someone given appropriate permission by the administrator in the access settings. The online documentation for dealing with the home page is found at
support.toastmastersclubs.org/doc/item/home-page
. BTW-Under the photo at the top of the home page, "attendance" is misspelled as "attentance."
