I often ask dreamhost support. I want to rate them well for their help.
However, I always go this message:
Sorry, you may not fill out the same feedback form more than once.
This is a sample of conversation:
Will do! I let my immediate manager know… hopefully something good
will come of it ;)=0D
Have a great night.=0D

Tell your manager that I wanted to give 10 rating. So this email =0D
should replace that stupid form.=0D
