Take your time getting your "shopper shoes" wet. It can be intimidating and exciting both at the same time. It was for me. Check out the different areas of this forum and continue posting.
Also, any questions or concerns about ANY shop or instructions, contact the MSP. The schedulers are more than happy to provide the answers to your questions and concerns, so that down the road it avoids any pitfalls, like a declined shop.
Hope this helps. Happy shopping and welcome.
