I'd had a brief thought today over the newsletter that's still mentioned on the website, and I'd wondered if that's still being used at it's advertised (Hearing about updates and well, news, ahead of time) if at all. I feel like it could be a nice way for the developers to communicate about things that're upcoming without the need for Forum posts or steam announcements, but that's just me having flotsam thoughts.
The other thing I'd thought about is the lore of Spiral Knights being explored through some small comics on the website, considering the game does have a pretty extensive setup (And some allusions towards Whirled) that could be expanded on and lots of question about Cradle and the Knights themselves that I'm curious about, and if Grey Havens' has considered it in the past.
