Lemmy Support

HI -- I'm wondering:

1. If support for private communities with a restricted member list within a Lemmy instance that is otherwise public is on the drawing boards for future implementation? Timeframe? Or just a someday since we are mostly volunteers?

2. If not, where would be the best place for me to submit this feature request?

Trying to weigh several factors as to whether or not to keep my Lemmy instance operational. My use case is I'm trying to attract an audience of users (mental health professionals) who seem to be just not interested in discussions on Lemmy if they are open to the public. If they want an anonymous account to discuss other topics (I allow these too), they can just open one anywhere. (Yes, I've done more marketing than most, but that's another topic.)

Thanks, Michael
