Sorry about being so pedantic. I don't think there's anything wrong about your reply, and the link is great. I just want folks to be careful that "It's cargo-cult" doesn't end up becoming a cargo-cult reply.FWIW his reply came over 20 minutes after several others that explained things in summary form, so a quick, short link was perfect at that point. If the OP wants to investigate further, great. If not, then there's no great time wasted reinventing an answer that won't be read, esp when merlyn did a good job already...
