If you mean the page like this page/groups-home then it's better to add the new method with sort by the groups' names. And it would be nice to add the new tab instead of using the currents (New or Top).
Actually that is really not enough. So even if they are alphabetize and sorted and you are viewing a group for Texas how do you get to the Tennessee group which would be the next one? You go back to group-home and then go several pages to find Tennessee and then click.
I have repeated asked for a back and next button when viewing this type of content.. albums, groups, posts, Events, Articles, etc. all should have back and next buttons.
