Is it okay for an undergrad to write a letter/communicate to the department that they support a professor who is up for tenure?

Greetings all. I have just completed an undergrad thesis with a faculty member of my department. The professor is up for tenure next year and I'd like to show my support if it would help; this professor is liked by all the grad students, helped me out a lot, supported me when I needed support and pushed me when I needed to be pushed. I don't know that anything I have to say would be taken seriously by the committee since I am only an undergrad but would it help, or should I just stay out of it? Thanks.

What you can do most to support the professor is to write a letter now to the Chair or Dean saying how much you learned from the professor and what a great mentor he (or she) is. Keep it away from the tenure decision/dossier because you do not want there to be even a hint that it was solicited.

The Dean or Chair can always suggest to the faculty member that they include the letter in their packet if the administrator thinks it will help their case.
