Are you following up with all new members? If somebody takes a tour of your opportunity, you should always follow up with a personal email welcoming them to the company. Make sure to let them know you are there for them with any questions they may have. You will find more success if your new prospects or members know that you are willing to help them achieve success. You must live up to it as well, if they need your help please help them. I have heard of too many sponsors leaving their members alone to learn about the business which can lead to them giving up. Many people have told me that happened to them and they were about to give up. It is very important for your success and your members success that you help them with their business along with yours. If you don't hear from them, check in with a quick email to see how they are doing and if they have any questions. Showing people that they are a person with a business and not just a number to you will ensure your success.
I wish you success :)
