nevermind about the link. it seems to work now.

Just a confirmation note on what happened to me.
1.) Was getting spammed by bots.
2.) Added registered user only hack (and tested it) so that only registered users could place comments.
3.) Still getting spammed by bots.
4.) Added the refferer check to the top of the wp-comments.post.php. This is supposed to stop the bots coming directly to the wp-comments-post.php file.
5.) Still getting spammed. The bots figured out how to get around the reffered code.
6.) Installed this hack. SPAM Stopped cold.
As far as I’m concerned about 99% of the spam is coming from these same scripts. They go directly to the wp-comments-post.php file. The only registered user doesn’t do anything to stop them, and the reffered check is not effective. This simple hack as of the present time will stop you getting spam, so it is the way to go. I’m leaving in the registered user hack, but I don’t think it is necessary.
thanks for this hack.

First I installed wellard’s wp-comments.php and wp-register.php. The spam kept coming in. The I added the $httpreferer check at the top of tehe wp-comments-post.php and the comments continued.
Redbug. I tried the above code, but got parse errors. When I cleaned it up and tested it I found that noone can post comments. When I do a test and logon as a user, the $user_nickname and $user_email is blank (at the top of wp-comments-post.php). How it this supposed to work.
I’m near stymied.

Ok this worked. What I did, following the advice from btvillarin was edit the wp-login.php file and insert the mb_language(‘English’); line as the first line in the function function wp-mail.
One thing I will note is that the line numbers referenced didn’t match the line numbers in my wp-login.php file.
After applying the fix the password is send in english, not base 64.
