Customize comments in wordpress

i want comment field to ask for name , email , text only (no website).is it possible in wordpress if yes how ?

 

Yes it's possible.

You would need to edit comments.php located in /wp-content/themes/yourtheme/comments.php

And simply remove this part similar to this:

   <p>
       <input name="url" id="url" value="" size="22" tabindex="3" type="text">
          <label for="url">
             <small>Website</small>
          </label>
   </p>

Code (markup):

If you need any additional help let me know.

 

why would you want to do that?
wordpress will not allow SER to follow the domains unless you tell it to

 

Why not?

If he wants to prevent of any spam comments being submitted.
