To notify only the thread starter, use the mod provided by John Lester (this one) and disable automatic subscription upon registration. Then open up the newthread template, find:

<input type="checkbox" id="subscribe" name="subscribe" value="1" class="dep_ctrl" {vb:raw checked.subscribe} tabindex="1" />

Replace {vb:raw checked.subscribe} with checked="true"

This way subscription is automatically off for everyone, except for the thread starter.
