After some testing, it's clear that the Web Collector Chrome Extension is set up to download single pages at a time. I was mistakenly hoping that it would follow links recursively and actually download an entire site (as can be done with wget - as described here http://www.linuxjournal.com/content/dow ... -site-wget ). This would be a great feature.
