A friend of mine is trying to sign up to PH on my advice, but is not receiving his welcome emails from which to activate his account? He's tried two email addresses and neither received the email.
Our mail server hit a blacklist (mainly on Hotmail), we have cleared off the majority but there is still one or two that could be affected. If he is on Hotmail then check the junk folder, if not then retry today as things should be better.
Did the same thing with me last week.... I think I sent about 4 or 5 emails to myself with no joy.... A bit of perciverience though and it appeared in the end...
