Apparently not - I can see each user's email address and I Yuku-PM'd it to make sure it is an actual address (and I've seen on his website that it is correct). Also, when you enter an email address the system checks that
someone has that address and returns an error if not - this is apparently what was happening at first.
I am unsure if he is getting past this stage i.e. has he got to the right page to send a password?
I've also typed his username into the 'Authentication reminder' box but he hasn't said if he got the email.
BUT at least he registered in the first place - there are many still to do this and I'm sure they're going to be even more resistant
