Is this possible? If I have only one ip address then changing the MX record shouldn't matter as it's the same as the www. But my email is on a different machine altogether.

I dont know which language/framework you are using, but with one submit button in any of them is a matter of checking the checked or unchecked.
You dont need 3 buttons, you need one button or none.

Answer Snippets (Read the full thread at stackoverflow):
A one-to-one or foreign key field on your Article pointing to your Revision, a column will be added__(self): return self.title
That said, it's rare that a one-to-one relationship is actually useful.

Use insert=false and update=false in one of the two.
Check to two properties mapped to the same column.
Allows you to join multiple tables to form one entity; that relationship can also be optional.
