How to delete a role/agenda item in the internal listing of roles

Who do you give access to mofifying the created agenda.
Once the Agenda is created using a template there should not be any reason to modify it other that assigning people.
Once again fix the old agendas to make your reports only show the correct roles.

RE: how to remove roles
1. open agenda
2. click on PENCIL icon to EDIT agenda
3. use the TRASH CAN ICON to delete a role.
 

To Richard's most excellent point of limiting edit power,  most clubs limit to VPE & Toastmaster of the Day... and maybe one other experienced FTH user who can help.  Those powers are handled in 2 locations and discussed in the FTH documentation.
