Marking communities as read only for yourself.

Ok this is going to sound pretty wierd but I think the use case is solid especially going forward. So with really specific communities that you are not really a part of that you are not a part of but would like to see what comes out of it. Well it would be nice to sorta be stopped from posting or replying. Maybe not completely but to give you a warning. So my example is there is a medicine community for medical professionals (this is a bit odd for me as I did work in blood diagnostics for a few years and have a micorbiology degree but it is a long ago and relative to my age short span of my life) and I don't view myself as part of that community. In some cases maybe I block the community if im uninteresed so I don't peanut gallery them but in this I sorta want to see them. So it would be nice to like mark it so I see posts and replies and stuff but as I said if I reply or post it might give me a popup that says something like you marked this community read only to remind me observing a conversation of professionals that expect to be conversing with people in their own field.
