I don't understand how can i create group of my hosts?

Somebody can help me, please?

Thank advance

Go to the host(s) you want to group in the "Host list", then select the group you want it to join from the list or create a new one by typing a name into the box. You can then add or remove projects to those groups from the "Group list", or assign a specific preference set to them.

Unfortunately, at this time it doesn't look like changing the resource share for projects within a group functions properly. Instead, the resource share from "My projects" is used for all hosts and groups. I've been trying to get that function to work, as I have a group of hosts (PowerPC Macs) that has some projects in common with my other hosts, but for which I want to have a different resource share. The only workaround I've been able to come up with, is that I can still adjust the resource share of projects that are only attached to group hosts, by changing the resource share for those projects on the "My projects" page. However, for projects that are on both the group and my other hosts, I must live with the same resource share.
