When I try to add someone to my group, nothing happens!

After a member of your group leaves the group, you cannot add them again. That's a protection against spamming users who don't want to be in the group. If the app tells you that adding a member is "not allowed" or nothing seems to happen when you invite them, it's because they were once a member of your group but aren't anymore.
To get back in, have them log on to groupme.com, and go to https://app.groupme.com/former_groups. Then click rejoin for whichever group they would like to rejoin. From there, they'll be added back in and start receiving messages over SMS or in the app (whatever their preference is).
The other options if they are using the Android/iOS app is to have them go into the global settings of the app and rejoin there under Show former groups.
Lastly, they can send a any text to the group number from their phone.
