July newsletter

There's a couple more things that need adding:

* The World Cup learning presentation
* Dealstruck job needs better link
* Phobio job needs link
* Mention Packt publishing?
I noted that in the PR. I need better links for Phobio and Dealstruck. I have an email out to Dealstruck but I'll just use their homepage if they don't respond. However, Phobio was an email from Trey. Their homepage is https://phobio.com/.
