Patrick,
I talk about querytracker on my blog all the time. I have a link to your site but I'd add the banner if you'd tell me how.

Go to design(upper right hand corner)on the right side click add a widget, add the html one and then put in the code for the banner you want.
The code for the one on my blog is:
<a href="
http://querytracker.net" target="_blank"><img src="
http://www.querytracker.net/images/banners/querytracker4.png" border="0" width="120" height="120" alt="Find Literary Agents and Publishers at QueryTracker.net" /></a>
Then preview it and see if it is where you want it on the page. Pat left other banners here
