I run a STEM group, my base line for success is more people being able to network and learn even small things or find someone who can help them,find new friends / contacts, rather than expecting people to produce something.
Hopefully we can start learing the GoDot engine, I know nothing about this, but there are enough resources on the internet to teach this. It will be a slow process so I am not going to put pressure on people,it is more plan sessions so they can watch a video for example
School / college / employment is about productivity, informal / casual groups are meant to be fun, so you could simply learn one very small thing, which is a big step.
