No, but I don't think it should be allowed, if we do. There might be too many Donors with the [Donor] Prefix. Being a donor is a privildge.
I agree with this donor is a privilege then everyone would be buying $5 and pretty much everyone would be gold. Noeone would stand out.
That would make the chat too colorful still, and it would cause complaints. We all remember what happened last time..
And also thats probably even worse because they have a different colour and would stand out EVEN LESS.
