getting values of checkboxes.

Hi all!

I have a problem - I have a list of checkboxes, with certain data...
the point is, that some of them are set, and the important thing for
mere is to get those values, which have changed from CHECKED to NOT
CHECKED.
Certain values are marked, once done, the user removes the flags, and
I need to know what was set to not being checked anymore (to remove
them from the task list).

But - I only get the $_POST value, it the item was checked.

How do I do it the other way?

Hmmmmm while writing this, I wonder whether I can use isset() -
whether the value is set, but just empty... will check tomorrow.
