1. You currently have three advertisement spots set up on the site:
1) The Leaderboard (#1) on home and interior pages
2) A right side advert (#11a on home, #6 on interior pages)
3) A lower right side advert (#8 on interior)
I'm not sure what structure you are planning for the Resource Directory, but we (or you)
can set up more ad spots inside that section if you wish -- let me know what your vision
for this section is and we can figure out the best approach.
There is no limit to the number of ad channels/spots you can set up. Once we get the
launch tasks out of the way, I will show you how you can control not just which images
appear on your current spots, but also how to set up new spots in the future.
To answer your other questions:
 Supported file formats for advertisement banners:
o Regular image (JPG, GIF, PNG)
o Animated GIF
o Flash SWF
 At the moment the exact (maximum) size of the leaderboard ad banner is 794 x 65
pixels -- however we can adjust the display of this if you wish, to allow a different
width and/or height (anything up to 800 px width).
 Once you have configured a banner, you can assign it to a space on the site by
editing the Advertisement content item that represents that space. Ad items
currently configured are: Leaderboard (2100), Right Ad upper (2117), Right Ad
lower (2118)
 Each Advertisement content item can be assigned any number of banners, and has
a property to set how many banners are displayed per view.
 quot;Rotational periodsquot; -- there are a few possibilities that I think you might mean by
this, all of which I believe PRISM can do -- let me know exactly what you're
picturing here and let you know how to work it.
 quot;Client database integrationquot; -- this sounds like something other than just
advertisement banners. Can you describe what you're looking for in more detail?
