Achat Beta is now available on the achat (not logged in) homepage.
It is “NOT” achat next, but a beta test version of the standard achat client.
First off, it is running on a separate network, so you will only find friends in public rooms and possibly private rooms if they are also running achat beta.
You can see people listed as online, who are on the regular achat client, but I did not try to invite any.
But I suspect that you would not be able to invite them, because people in regular achat public rooms, do not appear in the beta public rooms.
It will also act as a bridge between achat, achat mobile, and achat next, according to the banner at the top of the window.
Graphics are the same, no change from regular achat.
Poses all work, including B shop poses that did not previously always work in public rooms.
It may be faster transitioning between actions, but that might be a side effect of running on a different network server with less traffic.
It is supposed to be switched to in a few weeks.
It turns out that you can be logged in to both achat and achat beta at the same time with the same account.
Out of curiosity, I tried to invite myself, but it would not allow it.
