I've lived in the C++ world for years, and I'm just starting out with Ruby. I have a class that I would like to make a thread. In Ruby is it wrong to derive a class from Thread?

Is there a way for me to get to_yaml to produce the inline array version of the yaml? An options has...

If the page is viewed by someone who isn't a member of the site yet, the shared/comment_not_logged_in fragment should be passed in. However, I'm totally stumped as to why I can't run the same check ...
