I think, multi speaking support forums increase the users of Reaper.
Here in Türkiye, we discuss, teach, help etc. Reaper/Reaper users in just one forum. Most of the musician/producer learn the beings of Reaper by chance. Native language forums spread the Reaper. Also, increase usage and bug's reports.
I support multi-language for Reaper 'cause believe me or not most of the people are using the reaper don't know English enough for use the Reaper %100. Mean, they can't use Reaper's benefits.
