@JGoldman10,
Again, there is no such thing as a private site. There might be securities involved but someone has access to all your information. And there are lots of people out there who can get it.
Banks, credit cards, trading sites are mostly secure. But they've been hacked.
Someone wrote the security program. Someone can hack it.
And no, I don't post on private sites because I don't believe any site is really entirely private.
