I think it would be cool if series had the option to make news posts. It would also be useful to add series notifications too. This would help pretty big series make announcements, and it wouldn’t really affect small series either.

I like this idea too, but really, if you care that much about a series then they'd probably just post the announcement in a discord server. Still a cool idea though

You can, but it's probably not gonna be attually added since you're not supposed to follow series. Also give feedback in a support hub request since game pages, at least, are gonna be updated from the UI/UX interviews' feedback next
