How do I collect failed register attempts?

[agilent]

Is there anyway to collect failed register attempts?

I did download a "log logins hack" and it collects the actual logins of registered users onto my forum. However, I am wanting to know if it is possible to get the failed register attempts of those failing to sign into my forums. Would my ISP be able to provide me a report of all IPs hitting my server?

Any suggestions?

The reason I am asking is that I am getting a lot of people entering bogus screen names and password in an attempt to log in. I would actually like to know every time someone attempts to log into my forums or attempts to log into my forums.

Bumping this one up again.

This is real import that I find a solution. I really want to be able to help people who are trying to login into my site. If I could see the email address they entered, I could then email them back and help them.

Any suggestions?
