Why do some members of my group have grey profile pictures?
Updated
There are three different ways members might appear inside of a group
If a member of a group has a fully illuminated profile picture, then they have created an account as well as accepted their invitation to join.
If a member of a group has a profile picture that's dimmed, that means they have an Edthena account, but have not yet accepted their invitation to join.
"Pending Email Invitation" means that this person has not yet accepted their invitation to join the group, nor have they created their Edthena account.
