That's interesting. I got the e-mail, hit the 'register' button in it and got a generic 'registration successful' web page back. I tthought it was strange that no other 'confirmation' was sent to me, so I took a shot and kept that as 'evidence' should that be necessary.
I clicked on the 'register' link supplied by Red Roo to see if it would say "You have already registered". It took me to my QFF log-on and was allowed to (re-) register and this time I got a web page acknowledgment including my e-mail and saying I will get an e-mail confirmation. Hasn't arrived yet, but I'm fine with that.
Strange that the first attempt, off the e-mail, there was no e-mail or otherwise personal confirmation
