Firstly, thanks for even thinking of applying to this server. Please fill out one application per user account. The reason for this is I have built a white-listing system to handle auto-adding you to the server, as well as an email system.
If you apply for multiple accounts it breaks the system, so, your application will be rejected!
At this time applications are ONLY being accepted to the currently white-listed SkyFactory 3 server. This server WILL become public once FTB releases updates for security or I find a way to do that myself.
