2023-24 President is having issues when he is trying to logon to 4875.toastmastersclubs.org . This is the third time this is happening, he is not proficient in computers but he is improving.

Brian Jones DTM PM5 EC3 EH5 VC1 has indicated via a "Not a Member?" email link that they are no longer a member of club 
4875 and has requested that the system move them to Former Member status. 

This message is to notify you that the system has completed this request.

He is clicking an old link probably in an old email to get to your site.

Give him the correct link to save. 4875.toastmastersclubs.org
