Group names

Currently, when creating an event we are offered three groups of invitees:

1) Allies

2) In-group members

3) All members

I would like to suggest a change in terminology from "All members" because the difference between this and 'in-group members' just isn't readily apparent, despite being covered in the training. Perhaps, "everyone" is a better option?

Additionally/in lieu of a terminology change, perhaps include an "info button (?) <--- looks like that which conveys that "in-group members" only includes those who have designated themselves members, and that "all members" is inclusive of all who have joined the ERG regardless of designation.
