Mhm. Which build are you using?
I can only configure the "Invite Options" on Site Admin -> Invites. This are my values:
Invites Per User: 5
Number of Invites To Add: 1
Add Invites Every: 1
Invites Expire After: 31 days
The "Invite Stats" section below says that I have 0 free invites and that there is one user with 0 invites.
I don't see the Manage -> Invites menu with my test user account.
Update: I don't see the Manage -> Invites because the user doesn't have invites. However, I'm missing a menu item for the site admin to give invites to users or send out invites to a couple of people. It looks like that such a menu is not there.
The only code that looks like it could add such a menu is commented out in invites.php. Even if I uncomment the add_action nothing changes. Looks like the wpmuadmindefaultpage action is not definied?
function invites_admin_send_form() {
print "<h2>Invites</h2>";
?>
Invite a new user to use this site!
<form action='wpmu-edit.php?action=invite' method='POST'>
Email: <input type='text' value='' name='email' size='40'>
<input type='submit' value='Send Invite'>
</form>
<?php
// must also list stats on current invites and drill down into specifics.
}
# add_action('wpmuadmindefaultpage', 'invites_admin_send_form');
