[Q]: This video is fine for ballroom dancers, but it has nothing to do with the authentic Argentine Tango. Even ballroom dancing has now a separate category for Argentine Tango. Unfortunately, this video is not that. That's why, I rate it at 1.
[A]: Negative


[Q]: I can't share the enthusiasm of my preceeding reviewers.In my opinion, this is a book for advanced fishermen, who already know about fisheries ethics, or don't care about it. The book doesn't cover important aspects such as selective harvesting (how to keep damage on fish as low as possible so it can be released again) or treatment of fish, once it's caught (swift killing, keeping, cleaning).Two thirds of the book are about baiting, with major chaptors on how to use life bait such as small fish, salamander, frogs. However, the author completely fails to address ethical concerns about this technique("replace your bait frequently. When a frog tires and stops kicking, it is much less effective"), a technique that is actually forbidden in some countries because of the cruelty involved.
[A]: Negative


[Q]: I downloaded EZ Antivirus trial version from CA and Installed it on my laptop (XP Professional SP1). After installation the software started scanning automatically, which I allowed it to do and left my laptop alone. The laptop caught my attention when it started rebooting again and again. I realized my hard disk was also making a lot of noise.I went to CA's website and couldn't find any number to call. So I started web chat with their support. The support said that I might have installed the software with another anti-virus already working on my laptop. As per him, now only Microsoft can fix my problem. He said he would escalate the issue and copy me the email, which I'm still awaiting.To fix my hard disk I tried XP setup, Restore disks, and even reformatting the hard disk. Nothing works. I had to throw the hard disk.So just a friendly warning... stay away!!!
