There's a separate part of the forums that has been set up for you and the nine other members of your team. Only your team, and the admins, can see what is written/discussed here.
You can find it here.
Once you have all introduced yourselves and agreed on a start date, you post twice in the group daily for 30 days. One of these posts should cover what you have eaten throughout the day. Most of the members in this group have gone through a 30 day group before so they will be able to give you some top notch guidance as you go along.
