I vote yes!!
I do not support the idea of different badges or any public signs for different levels of contribution.
Not everybody has the same financial means. $5.00 may be a lot more than $100.00 to some people.
I believe people who truly want to contribute will send what they can.
Having different badges or acknowledgments may lead to a "who's better then who" situation. I don't think that we need that.
Just My .02¢
