Heyyo,
I say don't trust these sites. Scam scam scam. Like the IPOD ones.. do you really think they'd give away an expensive ipod to someone, for having 10 people register with them and pay like $5 for some small thing? lol, dream on guys. If so they'd lose huge amounts of cash, and go bankrupt. Internet's not a nice place.
Quick heads up: if someone online asks you to help them by cashing cheques at money mart (or something like that) and sending them the cash? don't, it's called something like a j-something scam... no it's not jihad.. it had someother name.. One middle-eastern guy approached me inna chatroom as a 21 year old chick.. using a 13 year old's photo and said (s)he was from new york, and was white, yet showed exceptionally poor ghrammar. Needless to say I checked around the net, and yep, scammage. Heck, in my town 2 people actually fell for it, but they were old and very trust-giving people. It's a sad place this world where asses take advantage of nice-people. I wish I could see the day when police bust into whoever's place, take him off to prision n' confiscate their computer for evidence. Tha'd show em'.
