Tech Tip

A few weeks back, ZDNet began a new column, Ask ZDnet, that was created by by my oft-mentioned tech whiz friend Ed Bott, which he writes along with other editors and experts. It answers tech-related questions from readers, but "tech-related" is flexible and occasionally borders on general knowledge inquiries that overlap with anything that may touch technology -- like questions on stopping chirping smoke alarms, how to send your taxes online if you're late in filing, and how to access online information is someone has passed away.  It's very interesting and informative.  You can find a new column every Friday here.
