Typo3 signal on change of fe_users table

Question

I have good experiences in writing extensions but I am new at signals and slots. I want to do something with users when table fe_users was changed. I can't find any example to start with. All examples are written in general. I can't use it yet because of my lack of experience in the field.

Answer 1

I solved it through the Middleware approach. It's future safe.
