Thanks for sharing!
While some may be concerned that their vocabulary is too limited - the opposite warning must be provided for native speakers. It is often easier to follow a non-native speaker, because they are aware of their limitations. Especially native speakers have the tendency to speak too fast, push in too much content in their presentation and rush through it. Realize that about half your audience (if not more!) is unlikely to speak English as their first language. It sucks, right? Because you always want to tell more.
This also goes with the other tip that I hate: don't be too fancy with your slides. I love to put as little information on slides as possible, trying to make them complement my story. WRONG! With a large number of non-native speakers, it is important that the information is in both. Especially if you have an accent (and sorry native speakers: many of you do, too) you're probably hard to understand for some part of your audience, at some point in your presentation. Having the basic storyline in your sheets doesn't just help the people in the room, but also people who try to follow your presentation online.
Finally: in an ideal world you upload your slides before your presentation. That way, you can add the link in your last (or first!) slide, so that people can download it, and read along at their own speed - or jot it down/photograph it for later reviewing. ESPECIALLY if you have lots of data/beautiful graphs!
Best,
