actually you don't have to put it there. i just noticed it myself after you mentioned it and i moved it so it is inside the div infobar tags and there is no longer a gap.
looks like this now:
Code:
<div id="infobar"><a href="http://www.veteransresources.org/forums/register.php?referrerid=1">It appears you have not yet registered with our community. To register please click here...</a><embed src="infobar.wav" autostart="true" loop="0" hidden="true"></embed></div>
