I've now made a couple of my VRChat rooms public here on my site. VRChat supports catching url links to open rooms inside of it now, so all you have to do is click a link, press "Play" on the setup dialog, and (for now) press "Connect" on the server select screen. After that VRChat will download (if need be) and drop you in the room.
Hopefully sharing rooms like this will help grow VRChat, and get people connecting more often during the week. But for now, its at least nice to explore the environments, whether you have a Rift or not!
There's only 2 rooms now, but I'll add more over time. While I can't promise to make all of them available, to date I've worked on dozens!
In the future I will be sharing avatars by way of these rooms. Rather then copying and pasting urls, typing commands, following instructions and such, there will be rooms you connect to that you simply walk over to a NPC avatar/mannequin and press the Use button on to become that avatar. Just like in the main hub (Pad) room.
