the actual skin file?

thats because it contains closing and opening divs that coincide with the other pages, adjust those other files as needed.

I think I just found out how...let me know if this will cause any other problems.

I deleted everything in the _feedback.php file and saved it. Everything seems to work and the form is gone. Have I solved the problem?

You could have simply disabled comments on all posts, but since you've found a method that works I guess there's no need to back up and do it over.

For a less destructive approach, open the _main.php file.

Under the section that says "START OF INCLUDE FOR COMMENTS, TRACKBACK, PINGBACK, ETC.", find this peice of code:

$disp_comment_form = 1;

And change the 1 to a 0.

Ahh...well, evidently, neither method (mine or yours) are working. I am still getting automated spam comments in my blog by the boat load.

Comment spam doesn't use the comment form is the thing. They go directly to the comment posting page and kick yer butt from there. Depending on version that'd be htsrv/comment_post.php. If you've removed the comment form from your blog (and scottsforum's method seems easiest) then I think you're safe deleting htsrv/_comment_post.php. You could err on the side of safe and simply rename that file to something like "die_spam_scum.php" just in case deleting it breaks something else.

Ok, I renamed it...let's see how that works out.
