Do we need to keep the licence on our website if we use this script?

Question

I am talking about the licence that says, "powered by question2answer" Can I take that out? I would rather not have it, but I will keep it if it is part of the rules.

I am confused because I looked at various websites that use this script and some have the licence and some do not.
