Is there any way of locking templates, so only admin can change these?

[Tracy Adams]

As I am sure everyone knows, in the early days it is quite easy to accidently change a template on add content to a template instead of a new card. Is there any way to lock these so a template can not be changed by other users, except by an admin?

@Tracy Adams If you have Business class then your templates have self-join disabled which means only team members you explicitly add to the board will have the ability to edit it:
