If you want to edit the default labels of the different types of text and objects in GivePulse, you can do so by navigating to "Customize" -> Look & Feel and selecting "Labels". You will see the following:
Note: The first column is the label name (default). The next two are what you want to change it to for both the singular and plural standpoints. On the final column, you can decide if you want this label to be modified through all your subgroups inside your "network" or if the change should only take place in this specific group.
Note: Subgroup labels can be modified; currently, you have to select from the pre-created selection of options.
