I want to write a WordPress Plugin. I have read some of the documentation about how 'hooks" work but I do not know which hooks to take advantage of. I want to write a plugin that launches a separate page when a new user wants to add a new comment. In other words, I want the ability to insist that the user add more than just a username and email. I want to require that more information be inputted. Maybe such a plug-in already exists or perhaps something simular. Does this sound familiar? The Plugin I want to make is a page that comes up after a new user clicks on the “Submit Content” button when posting a reply to a blog. What sort of Filters or Hooks to I need to use? I have been told that I wouldn't necessarily need another page. I could just more options in the regular comments area if I just want to the user to input more information. If so, could I include a couple of buttons that would launch the "about us" page in a separate browser?
