link is now located after the page title at Your Organizations
form only asks for Organization name - owner is automatically set to the current user and the slug is auto-generated (with integers appended if necessary for uniqueness)
Editing an existing organization only allows you to alter the name.
Feedbacks show author's username instead of first name and last name.
Decisions can now be moved between Organizations by editing them in the django admin screens. The admin user will be recorded as the last editor. All members of the new organization are added as watchers for the Decision and all of its Feedbacks and as this happens before the notification stage, the members of the original organization won't get notified of the change. Intended refinements to this are listed at https://aptivate.kanbantool.com/boards/5986-econsensus#tasks-1533249.
Thanks to Sarah and Phil for their contributions above :D
