Enable members Send topic to multiple friends at Once

[Harry33]

Hi there my original post can found here http://simplemachines.org/community/index.php?topic=403804.0. How can I tweak the emailing on my board so members can send topic to multiple friends at a time. They complained emailing one friend has become boring to them. Thanks.
