AMD is pulling a page from Microsoft's book by introducing the Radeon Software Vanguard Beta Program. By subscribing over here, Radeon video card users will be able to beta test drivers that aren't available to the general public.
This looks a bit similar to Microsoft's Windows Insiders program, although it seems like AMD's program will be more closed. More details should be available on the Radeon Software Vanguard later today, it's not online yet.
The Radeon Software Vanguard Beta Tester program aims at opening a channel for selected participants to work directly with AMD, giving a voice and platform to share their passion for Radeon Software.
