Lynn,
There are a couple of mode of operation for MapServer that are available. You can communicate directly with it via a CGI request, or it can be scripted via MapScript, which has many binding flavors.
We use the CGI mechanism quite extensively in our own service work as well as GeoMoose, a Javascript client framework which accesses MapServer CGI amoung other things.
Maybe we can help with some of you questions.

I am writing an article to discuss the use of geospatial technologies in education. I have used ArcIMS extensively and want to discuss MapServer as well. However, my expertise in programming and setting up server applications is pretty limited. Actually FORTRAN 97 in 1998!. So I find myself in over my head trying to compare the functionality and ease of use of ArcIMS and MapServer. Additionally I am trying to find some examples of MapServer to explore.
I was hoping you could direct me to a few sites running MapServer and perhaps put me in touch with someone I could talk with about MapServer.
Respectfully

Can you get the scale value MapServer is using on a map where you think there should be
annotation for this layer but there is not? Easiest way to do that is with a simple browse
template like so:
<!-- MapServer Template -->
<img src="[img]"><br>
Map extent: [mapext]<br>
Scale: [scale]
Note that you'll have to set IMAGEPATH and IMAGEURL in the WEB section of your mapfile. Then
you can call the CGI like so:
http://.../cgi-bin/mapserv?map=yourmap&mapext=extent where things go away&mode=browse
If all goes well you should see the generated image and the computed extent and scale. I'd be
curious to see those numbers on a problematic map for 5.2 and 5.4.
