Tom Spring at PC World tested the cancellation policies of 32 web companies—including two that genealogists might use. The results: canceling Ancestry.com was hassle-free, but Classmates.com needs some work.
I couldn't find any information on how to cancel until I entered the word cancel In the site's search engine. Classmates.com spokesperson John Uppendahl confirmed that there is no other way to find cancellation information. But that was only the first hoop I had to jump through to cancel my membership.
Classmates.com also forced me to click through several Web pages reminding me of the benefits I'd lose. Finally my clicking ended at a generic Member Support e-mail contact page containing a blank 'Your Question' field. Though the form said nothing about cancellations, I used it to request that the service cancel my subscription. [Link, via Boing Boing]
