Uploading or copying and pasting a list of people to invite them to a group. For people with multiple add to group requests this is a lengthy process and very time consuming.
Send out personalized group invite messages when adding new members. If you don’t get to add a new person right away they can forget they sent the request and then you have to explain why you’re sending it to them. For people with a large amount of requests again, time consuming.
Add an option for hiding group members to people within the group. Some people join groups for no other reason then they have high numbers and want member lists. This will stop list stealing.
Add a picture section to a group with a teleport option. So people can see what the group is selling, land sales, rentals, members, the lands, etc and teleport to them.
