“Excited about your masterclass and the positive impact it’ll have on the testing community and beyond.”
The “and beyond” bit made me stop and reflect.
It’s something I just wrote in an email to a community member off the back of
a call discussing an idea for a masterclass they’ll run with the community I advocate for.
I reflect that as a community advocate and full-time community professional, I tend to focus so much on the community I advocate for that I forget about the customers of the community I’m advocating for. What happens beyond? 
In my context, it’s a community of practice for software testers (Ministry of Testing). So any learning opportunity for a community member has the potential to have a positive impact on the customers they are building products and services for. And this particular masterclass is on accessibility.
It’s a good reminder of the positive impact community can have far beyond the community.
