Hello, thanks for making this thread. Our bedrock network does not have support for /register or the report website yet. This is because you cannot click the links in the chat unlike Java edition. We will be looking into allowing players to link their bedrock accounts to our report website in the future, but as of now, you'll need to either report players on our discord server in the #staff-help channel. Or email
support@cubecraft.net with solid evidence.
As for the Minecraft version, you're using Beta 1.10, our network does not support that version yet. Please use a retail version, which is 1.9.0. You will need to leave the beta programme to access our network. Thanks!
