OK, after testing, changing, testing testing and testing again I can now report that the Paypal payment system only upgrades about 50% of the payees, and there is no improvement. The problem is that only 50% of paypal mails "yes this user paid" are ever sent out, and that's something Paypal only - not me - can fix. I'm throwing in the towel on that now, as paypal is rather (read extremly) nasty to deal with anyway and such dismal numbers are unacceptable. The Secure Credit Card [1] system is considerably faster and works 100% of the time so we might as well just keep that.
On another note, June is almost up and that means there will soon be a new guest writer at Coudal.com [2] where I've been dropping links the past month. Pay them a visit, the links are mmm-mmm-goood, and their photoshop tennis [3] games are great friday fun!
