[wp-hackers] How to send information to the plugin?

[Eduardo Nordmann Bazan]

I'm making a plugin that lives inside a page and needs input from the user.
I tried to get information from a form but without success. I think the
problen is that the action field ot the form is not pointing to the rigth
address.
I haven't found any solution for it in the codex an neither making a search
in google. Any idea?
