This is the form that posts to the partylist. Using this form ensures that your notice will be in the correct format, and will have the right attachments. You need to be a member of the Partylist to post to it.
Anyone can join the Partylist, so you might want to keep your address out of the actual notice, and email it to people who ask for it (assuming that you know them or know of them). You can join the Partylist here.
