Paypal is driving me nuts.

Why is Paypal so disorganized?
If you’re a developer, there are something like 6 different sites that are for use by developers. x.com, paypal-community.com, something called custhelp.com (which I was referred to, and sure as hell looks like a phishing site. Or something written by a 12 yr old).
All I want is an answer to why I’m having a problem posting an invoice to their ExpressCheckout, and I’m getting attitude and BS back.
