Stephen, this is a great idea! If you would like to share Flexviews within the community, any file sharing application (Box, Dropbox, etc) can be embedded into a reply. All that is required is to make sure what you are sharing is a public document and then the community can benefit from this. If you would like to share your in this fashion, please feel free to do so in this topic!
I am not entirely sure about sharing them in Netsight. I will share this idea with our Product Management team and they will update. Thank you!
