Marco is currently the head coach in the community, backed up by the mighty SteveM and Grumpy. If you have any coaching questions, they're the guys to ask. Feel free to ask as many questions as you like.
Sunny's here to help with any membership issues, tech support, or purchasing questions. If you want to extend your membership, update a credit card, or buy a discontinued program, you can reach him at firstname.lastname@example.org
DanielK is here to help guys get set up in the community and track their progress. If you've got any questions about the community or need a moderator's help, he's your man.
As for me, Shane, I'm focused on producing more content on bonytobeastly.com and outlift.com, and on updating and improving our programs. I'm still in here pretty often, but Marco is the head coach.
As for where to start, start by making an introduction post. Post your before photos and goals, and ask us all of your questions. We're all here to make sure you get the best transformation possible :)
