User registration for comment

Hi,

I would like to ask about the registration process to be able to comment on articles in my site phstocks.com.

It’s funny because for a few times I received and approved comments. However, when it is I who tried to post a comment (of course I logged out of my dashboard), I did not receive any password when I tried to register to make a comment.

The registration process, as I see it to make a comment in my site, includes filling in a username and email. And then a note says “A password will be e-mailed to you.”

When I did try to register, I did not receive any password.

When I clicked on the “Forgot Password” button, and then submit the email address I entered for registration (I tried this a few times for my other email accounts) to get a new password, the message is:

“The e-mail could not be sent.
Possible reason: your host may have disabled the mail() function…”

So, may Iknow how this works, and may I know what I am doing wrong?

Thank you.

Richard
