Randy O'Meara sayeth:
Todd, the sample files are not available at http://www.math.utexas.edu/~toddg/docs/psets/6916.ps1-pg.tar. Have they been moved to another (accessible) location?
Err.. yes. Good thing you noticed, I wouldn't have for the next several months. They're around here somewhere (I hope they're not still on my home machine in Texas). I currently being paid to work with ACS Classic, so I haven't monkeyed with OpenACS in a while. I'll find the files soon - maybe as soon as this evening.
On a totally unrelated note, does anyone here live in the Bay area, and need housing or tenants?
