It is correct that not all LLL Leaders are listed on the web site. This could be for several reasons such as,
- new leader not yet listed
- leader who does not want to or is unable to take phone calls currently
Some leaders have taken phone calls in the past but may not any longer due to volunteering in other areas within LLL. It is a very large organization and there are many roles to fill, including administrative and what not. So some leaders fill the administrative roles or work as help and support for other leaders, such as the ones that are actively involved in a group or taking phone calls.
So yes, you can most certainly be an LLL Leader without being listed on the website. Any other LLL Leader could inform you of whether or not the woman you spoke with was legit. Leaders have access to a leader only database with a list of all current leaders in their state and their information (at least here in Florida). That list is just not available to the public.
