I tried to search several times on the forum but couldn't find any info about how to use the collaborative world editing feature.

On the website I watched the video but it uses a tool that I don't have called the version control server.

Is this something we need to create ourselves or is it a tool that is no longer available?

I'm a bit confused as to how to do this.

The tool is now called Data Server. Never used it before though.

aaah, ok, thanks.
