Nice one Paul!
I like the length - short and snappy, but good takeaways.
Next one maybe continuing the theme of communicating value but with references to pitching to sponsors? e.g. how to properly communicate the value of your event/audience to a sponsor.
(Had a sponsorship proposal in my inbox today that I thought was very poor - no thought put into why they were emailing me/the company and how to personalise the offering for us).
