 The Dashboard group admin panel includes an interface for adding users to
 groups. This interface is a text entry field that expects a comma-
 separated list of user_logins. The field has autocomplete support; the
 server-side handler is
 https://buddypress.trac.wordpress.org/browser/tags/3.2.0/src/bp-groups/bp-
 groups-admin.php#L1236

 If you are running a large multisite network, the UI behavior is poor:
 - When you start typing, a spinner gif appears, and an AJAX request is
 sent. But the AJAX request fails with `-1`
 https://buddypress.trac.wordpress.org/browser/tags/3.2.0/src/bp-groups/bp-
 groups-admin.php?marks=1244-1246#L1236. So you don't get any autocomplete
 results, and the spinner never stops.
 - Since you can't select autocomplete results, you've got to enter a
 user_login (or comma-separated list of user_logins). But there's no way to
 know this by looking at the interface - I only knew because I wrote this
 interface originally, and even I had to open the codebase to figure it out
 :)

 I'll post a patch for what is, I think, a minimal fix.
