I'm a post-AGDQ 2017 newbie, and have been exploring the various series speedrunning discords in the 12 Hour Challenge spreadsheet (https://docs.google.com/spreadsheets/d/1UjEcE5USS3wF6SuDGI36M-FfGZUnOjGq243X0M8Zlvg/edit?usp=sharing). Is there a Discord for the Sparkster series?

Indeed there is! I'll post it here and also update the forum pages for each game with the link, thanks for bringing this up.
