Some user experience registration problems.
THe way it works is that after the registration is complete, a confiramtion mails is sent to the e-mail address entered.
Now if the e-mail address is incorrect, or mis-spelled, obviously you will not get any mail, thus you will not be able to login.
Same applies if the mail is catched by a spam filter, so please check your spam-box.
The confirmation mail should arrive within a few minutes.
Some ISP's use a spamfilter system that requires the sender to confirm the mail, well, since the sender is the server it obviously cannot confirm it, so the mail will be lost.
If you are using such a service, please get another mail account with one that does not.
Other problems please drop me a mail
