Hi Andy,
You're welcome to join us. We don't ask for any specific skill, so in worst case you'll feel a bit lost and we'll be there to help. I believe it will be a good chance to see how people work and that you won't find in any tutorial.
Please feel free to tell me if you don't feel confortable enough to code if I ask you to pair up with someone. Apart from that, I hope you enjoy the experience.
Cheers,
Ivan
