Isn't it possible to have free and paid voting at the same time?

I'm trying to give everyone an option to vote for free. At the same time, people who want to increase the chances of a certain photo should be able to buy votes. I enabled "Participation fee / donation > Sell votes". It's not possible to vote for free now. Correct?

Hi,
You are right:

• When donation is selected, you can only vote once and donate for the one participation.
• When selling votes, you cannot have a free vote.

Kind regards
Philipp
