I made a mistake when I first signed up. I'm just an individual not a company or a team. All I want is for people to put their username for 30 minutes time slots. I mean their username on a particular site where I'll be putting calendly. That's all I need, I don't need their real name or their email address. I added a category to put username but I can't delete the default categories of first and last name and email address. Also it thinks that I'm using the free trial of the paid service and I don't want that. I just want something simple where people can go in and in 30 minutes increments put their username in a time slot.
