This comment isn't about this blog post but since I couldn't find any contact information on rubyplus.org, i thought i'd leave it here. I signed up for an account on rubyplus.org, but if I visit any of the screencasts actual pages, I can't download them. It just tells me to 'sign up to download for free' when I'm already logged in and everything. Just thought I'd let you know about it.
