anglin_fool asked What do you mean by number three?
Once you post your message with the
attachment, right click the attachment
link and choose "Copy Shortcut" (if you
have Netscape, click "Copy Link Location").
This is what you paste bewteen the
quotes when you edit your post again.
Or you can do like Ratboy suggested and
just load the attachment, then copy the
address from your browser's address window.
