To create an account on this site you need to provide a valid e-mail address. That is quite a common requirement for many sites these days and helps use reduce the number of accounts created by bots for spam purposes. Many people are using their own forms of spam protection on email addresses such as the challenge response system where you send an email to someone and they automatically send you an email to validate the address the original mail came from. This can be a great system and works well for personal mail. Sometimes just clicking on a link is enough to validate the mail others use captchas or other forms of validation.
Let's suppose the following occurs, my automatic system sends email to your automatic system then your automatic system sends mail back to me to validate that the original email was from a valid source. This can be a common scenario as more and more people try to combat spam. Now let's say we get between 20 and 50 new registrations each day, and let's also say that I haven't worked out how to clone myself and that I have other hobbies apart from filling out captchas.
What I am trying to say here, in case you haven't been able to read between the lines is that if you use a challenge/response form of spam protection, make sure you have a way to by pass it at your end so that you don't wait for me to respond to your email, as I usually wont get around to it :rolleyes: .
