Access to Club Website "Springfield Lakes Toastmasters"

I am the Immediate Past President of the Springfield Lakes Toastmasters Club, and am submitting this request on behalf of our executive, who asked me to do so at our last executive meeting.

Our club website ( 657601.toastmastersclubs.org/ ) was administered by a member who passed away at the beginning of last year. None of the current executive previously had access to administer the website, and so we have lost access to it. This is a challenge in our present efforts to update all of our online contact points and information to reflect recent venue and membership changes.

Could a site admin, moderator, or other appropriate person please advise us on how we can regain access to change our club website?

Here is the documentation on how to change the site admin:
