Creating my focus group

To help me with the process of planning and producing my own music magazine I have created a focus group consisting of people that are representative of my target audience, made up of 20 peopl, 10 boys and 10 girls, who are between 16 and 25 years of age that have a range in interests in music.
I have asked them for any opinions based on my decisions for the magazine, and by using a focus group consisting of people from my target audience I hope it will make the magazine more appealing to my target audience as I will have a wider point of view.
I will keep in touch with my focus group using Facebook, creating a group chat where I can post questions and decisions that would like them to voice their opinions on. A group chat means they will also be able to send in any ideas they have for the magazine also.
