My advice is tread carefully. I went to the home site of this person following a link relating to biting that ran at the top of this forum. There was an interesting video clip then, if you want all this amazing advice and a free video about training your bird to do x,y & z then type your email into the box and we'll put you through to the link.
At this point I was smelling a bit of a rat. I have to say I'm one of those skeptical people who doesn't believe there is any such thing as a free lunch, but I still put in my email address #rolleyes# . There followed page upon page of 'selling' his patented video course followed by letters from people who had had success with it. Skim to the end and you got a 3 figure sum for the course. At this point I left the site feeling a bit conned as the 'free clip' offered wasn't on any of the points that it said it would be on.
I thought no more about it until I opened my mail box. Since then I have been spammed within an inch of my life, previously I only received the odd one. Thankfully my security is tight enough to jump on it before the virus loaded junk got out. Also my credit card was used fraudulently on line and has since obviously been canceled .
Now all this might just be one BIG FAT COINCIDENCE, but as I say I am a cynical person. Make up your own mind but make sure your security is up to it before you type your email address anywhere you don't normally go.
