USS Alpha needs members.

To be a alpha member you need to provide quality reports and they might invite you but at this stage they are not inviting new alpha members as the alpha ring is full but usually every 6 months they invite new members to alpha so the best way is to wait
and submit reports

You will need to be a member of the Xbox Insiders to do this.

Unfortunately Avatars is only for Alpha and Alpha step ahead members (which is by invitation only).

If you are still interested though, you can build up your score to go through the different levels by providing feedback on questionnaires and bug reporting.

The more points you get the higher rank you can achieve to get higher placing in the program.

Once you have hit BETA level, give valid and constructive bug reporting and you could be picked for the Alpha or Alpha skip ahead group.

This will take a little time, so dont expect to be in Alpha within a couple of months, most people have been in Insiders for maybe 6-18 months before being picked for Alpha groups.

A Friend says its since 31th july in but only for alpha skip ahead member realese of only Alpha is coming

The Chromium browser was previously only available for members in the Alpha Skip-Ahead ring, but as of the last couple of days, it's not only been rolled out to Alpha members, but also Beta and Delta members. Only the Omega rings have yet to receive it.
