Hello. How can install this interface?!
were can i found ?!

As plugin/modification nowhere i believe; comes by default on a MyBB 1.4 installation.
You can become a beta tester if you want to have it now; else you need to wait until the final release.

Yes i want. How i do?!

it is 1.4's editor. When 1.4 released, you will have been using it on your forum

Done. Thanks everbody !!
