I'd like to have a custom global or plugin written that automatically redirects a user after they successfully rate, comment or login, to send them back to the page they were on before they chose to login, rate or comment. So, if they are on a category page, choose to rate a link, once they successfully rate, they get sent back to the category they were on before the rating. Same for login and also comments. If it is much less expensive to simply have a link on the rate/login/comment success page, that would be fine too. Thank you!
