Hi, I've been off the site for a while. I'm reading about the new CW system, and it says it will be "part of Subeta v2". What is Subeta v2? Where can I learn more?

Staff are working on recoding the site, so revamped areas are being moved over to the newer, work-in-progress version of the site. The Wardrobe and Custom Wearable pages are the main ones there currently if you want to see what it looks like at the moment, but it's very much unfinished and you can't access very many (if any) other pages besides those on that version of the site. I don't know off the top of my head if other pages work there or not
They're giving most of the updates through this subforum:

Welcome back!
The main thing to keep in mind is that the only way to get there is to do something with a purpose and the links to it are already smooth from Subeta v1. There are no accidental stumbles in or out of it.
There is no "back to Subeta v1" button. If you are done playing in v2, you can close it out. I find it useful to open up a new tab whenever I go there so that when I am done I don't lose any of my working pages.
