accessing the $post template

In my postbit template, I see references to $post[aim], and other such things in the square brackets, how do I access $post and edit its contents?

Thanks,

if you are tlaking about editing the aim,yahoo,and icq icons it can be done by editing their respected templates.

and if you want to edit the other $post variable you have to open functions.php and go to section getpostbit

I'm actually trying to change the profile, www, pm, add to buddy list icons into an imap. Do you know which template (or file) I'd change to do that?

Thanks,
