I just would like to know if it is acceptable use of this site to have resumes or cover letters critiqued with of course all the personal information removed. Is that acceptable use of this site?
No, that is explicitly off-topic per the faq:
"Please review my resume/CV" Questions need to apply to more than just you. Since this site is here to help everyone, and not review to a specific resume, these are not "questions" to us as they don't have definite answers.
