finding the "post" function

[inmolatus]

Hello everybody,
I am looking for the function that allow users to post comments due to the fact that I need to put there an antispam function to allow unregistered users to post comments. I have been looking for it and I haven't find it.
Any idea of where can it be? 
Thank you very much for your time.

Hi,

I need to put there an antispam function to allow unregistered users to post comments.

look the captcha plugin http://forum.coppermine-gallery.net/index.php?topic=36319.0
it's not necessary to modify the code for this  (next time use the search function befor posting  )

Thank you Frantz but I have used captcha plugins and I realized that some bots are able to break it. I found a way that allows you to create your own questions/replys before post the comment and till the moment its the best option I found.

I find it hard to belive that bots are able to break the captcha auth. Post a link to your gallery for a start. You might want to take a look at the akismet mod as well.
