Team 2655's 2010 Website

Hi,
I’ve already posted the site on the web competitors thread But now I have a few more questions.
Here is the website: http://team2655.org/index.html
Any feedback you have would be great!
And now on to my questions…
The first one is about copywrite information. I’ve searched the forums for this information but I have been unable to find the thread where I’ve read such information. When using Gracious Professionalism do I need to add the trademark symbol? Also, when posting a video of the 2010 game animation do I still need to e-mail NASA for permission or is there a catch-all copywrite statement for it.

Next question is about code. This year I’m trying to have my site completely w3c schools valid and I’m slowly going through my pages and adjusting the code. When I came to pages with youtube videos I had to find an alternate method for embeding them. I then found this nice little code:

<p> 
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash
/swflash.cab#version=7,0,0,0" width="480" height="295"><param name="movie" value="http://www.youtube.com/v/AsoImp0Ao-w&hl=en" > 
<param name="quality" value="high" ><param name="bgcolor" value="#FFFFFF"> 
<!--[if !IE]> <--><object data="http://www.youtube.com/v/AsoImp0Ao-w&hl=en"
 width="320" height="265" type="application/x-shockwave-flash"> 
<param name="quality" value="high"><param name="bgcolor" value="#FFFFFF"> 
<param name="pluginurl" value="http://www.macromedia.com/go/getflashplayer" > 
If you can read this your browser cannot play Flash files.
</object><![endif]--></object> 
<!-- Code From Hixie's Natural Log --> 
</p> 

The problem is that it is XHTML valid but not HTML 4.01 valid. When I run it through the validator it says

“ENDIF” is not a reserved name

Any suggestions on fixing this?
Thank you.

try taking out the endif and on ur site try moving the navigation bar to the left to be lined up with the first logo it will be more appealling there

Take out that code. Use SWFObject to embed flash content on the website.

Thank you so much! It works nicely.
