Here is a link to my branch that implements Custom Fields for both Ticket History and My Account.
http://github.com/rmiddle/cerb5/tree/jira/chd-1782
Noticed the password field isn't working.
Address + Org custom fields are now available in 'My Account'.
Update this forum post when custom tickets are added.
