Private group for whitelisting access to SteamWorks game servers

It was being used very specifically for access to servers which are now no longer relevant. Additionally, I have gone though a name change, so "Yuki" isn't current either.

I've created a new group to use, and I invite everyone to request to join here, if you still want access to SteamWorks games that I host (currently only Space Engineers).

At some point in the future, everyone will be kicked from this group and it will be deleted.

Thanks!
