Like other plugins I have used, I prefer to see the wp users in first name alphabetical order and to be able to use browser's ability to select items from a form by entering the first letters of a partial name.
To enable this I changed two emu2 programs. The "<" is the new change and the ">" is the old. These changes would have to done manually because I had to convert the programs from windows/dos line ending to unix/linux endings. The two programs and changes follow:
1. emu2_user_mail_form.php
(This is in main code not a function)
02c102
< <?php echo __('', EMU2_I18N_DOMAIN) . $user->display_name; ?>
> <?php echo __('User', EMU2_I18N_DOMAIN) . ' - ' . $user->display_name; ?>2. emu2.php
function EMU2_get_users()
649d648
< $order_by = " order by display_name ";
659c658
< . $additional_sql_filter. $order_by );
> . $additional_sql_filter );
672c671
< . $additional_sql_filter. $order_by );
> . $additional_sql_filter );
