From World > About Land > General Tab
If land is owned but not deeded, and set to a group, one cannot open the group via an info button, like you can if the group is the owner.
This would be a nice feature, it was present on the old gui phoenix viewer.
Turns out there IS a button to open the undeeded group but it is placed across from the maturity rating instead of across from the undeeded group name, obscuring it's function. Its location does not seem obvious, at least to me, after using singularity for quite a few years.
This looks like a mistake, we'll fix that.
