If you want to make donations for Rena's expenses, (e.g. helicopter to CO Springs, and I don't know what else, but there will be expenses, even daily expenses that haven't been thought about yet), then:
The donations link at the top of the page is fully functional. You will know you are on the right page because it says her name on it and shows names of other donors on the left. There is a separate bank account set up for Rena exclusively attached to it, managed by family members until Rena is able to do it herself. All donations will go to Rena's care, rehab, and living expenses.
