Moderators with proper permission can add manually members to raffle but this won’t generate an invoice for the members. If the raffles allows one ticket per member, then only one is allowed. If it allows more, than a input box with a number will show up. Default to 1. Max = maximum number of tickets per member. But I’m not totally sure about this last part. That is what happens when purchasing tickets; not sure when adding manually. Would need to install the app and see.
