Hello. Putting the price as $0 will accomplish what you want. To get rid of "Free", simply go to the DT Reg configuration on the event listing tab and set it to NOT show the event price. That will remove that column completely. You can also choose to not show the price in other DT modules, calendar popup, etc.
Within the registration process, if there is no fee, no pricing details will show. Then you can just put whatever info about cost that will be collected later... and put that in the message above the registration form... in the final thanks message... emails, etc. Thanks.
