It's good to have communication with their members, because they inspire confidence and get to know you, it is easier to ask for your help. Of course you can make your blog about the job and the simplest way to describe your job to someone who is not familiar with SFI easier to understand. You can add a video, and then send their new members to your blog where they can find everything they need, and then you can by sending it to a user. I hope I've helped
