I don't have the strength to go through all 400 pages of this conversation to see where I fit into it, but It's nice to hear someone else mention the awfulness of the RM message system. Not to mention, @Eric Hassan, the fact that users literally have no idea who has access to view/intercept any of those communications. When I've worked for other companies with proprietary messaging systems like that, administrators (at basically any level) had access to view/edit/delete all messages on all sides.
So if you're relying on Rentmen to keep your secrets for you, I've got some troubling news.
Clients reading this and friends who might communicate that way: please be patient with providers who ask you to use a secure messaging system. You can't imagine what a struggle it is to be called names and shouted down for refusing to make plans or discuss details via Rentmen messages or SMS. It sucks so badly to be trying to do something eminently practical (and for everyone's good) and be told to "go fuck [my]self, princess" because "everyone else [they] deal with does it this way."
I don't have any beef with the "princess" part, but the rest of it makes my job harder, and puts your safety in jeopardy.
