Hi,
login as ste admin and go to dashboard > Groups (wp-admin/admin.php?page=bp-groups). There will be a list of all existing groups. Click on the one you want to asign members.
Eventually open screen option tab (underneath top right corner) and ensure that add new members and members admin options are checked.
Below the group description field, you have another box where you can enter a username for the member you want to add. Normaly you’ll get one by auto-completion after typing a letter or two.
That’all.

thank you Dan – i saw this, and felt that it’s unfortunate that existing users have to be manually typed in instead of being provided in a simple dropdown, and that multiple users would have to be assigned to a group one at a time in either case. Surprising that BP is stuck with this archaic format in this instance.
just sayin’
