This question comes from Twitter from: Kyle Redddock, @WinPhanKyle
He wanted to know how to change the group name of the site columns through central admin.
This is not possible through central admin but its pretty easy through powershell.
The first thing you have to know is that you can not create a group of columns, the group name is actually a property of the site column itself, and once you change all the group names of your site columns, then you will all the columns grouped under a different group (if that makes sense)
$site = new-object Microsoft.SharePoint.SPSite(“http://xxxx:4000”);
$site.rootweb.Fields[“TheColumnName”].Group = “TheNewGroupTitle”;
