Internet Explorer support in Discourse to end June 2020 - will this affect any DHI Networks members?

While I sincerely hope DHI Networks members are all safely and securely migrated to a more modern browser (Chrome, Firefox, Edge, etc), I’m aware that such things can happen slowly in the real world of the NHS.

Discourse (the forum software which the Networks runs on) is planning to remove Internet Explorer support from June 2020. Is this likely to cause issues for our user base? If so, it looks like IE support might be able to be ‘retrofitted’ as they have moved this stuff out into a plugin, which I can add to our instance, but of course if this affects nobody then I don’t need to add it.
