[SkyCatcher]

Well... first search for the hack that enables you to post html for usergroups. Then enable yourself to be allowed to post html and then use embed tags in your post...

PHP Code:

<OBJECT classid='clsid:D27CDB6E-AE6D-11cf-96B8-444553540000'
        codebase='http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,0,0'
        width="587" height="57">
        <param name='movie' value="movie">
        <param name='quality' value="high">
        <param name='bgcolor' value='#FFFFFF'>
        <param name='loop' value="true">
        <EMBED src="YOUR FILE HERE" quality='high' bgcolor='#FFFFFF' width="587"
        height="57" loop="true" type='application/x-shockwave-flash'
        pluginspage='http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash'>
        </EMBED>
        </OBJECT> 


You should be able to modify that bit of code there and put it in your post
