User Profiles

I’m trying to figure out a few things – I’ve done a search and read through a couple dozen or so items without much luck.

I’d like to incorporate some more info into the bbPress user profiles – I know I can probably do this using the $curauth params but want to make sure. I also want to make authors/contributors/etc link to the bbPress profiles as well. Is there a quick piece of code I can use to do this within my WordPress theme files?

I have this function to return an author profile page when the name is clicked on:

function new_comment_author_profile_link(){

    /* Get the comment author information */
    global $comment;
    $comment_ID = $comment->user_id;
    $author = get_comment_author( $comment_ID );
    $url    = get_comment_author_url( $comment_ID );

    /* Return the default WordPress comment author link if comment author is not
    a registered user */
    if ($comment_ID == 0){
        if ( empty( $url ) || 'http://' == $url )
            $return = $author;
        else
            $return = "<a href='$url' rel='' class='author-url'>$author</a>";
    } else {
    /* Return the link to the comment author's profile page if otherwise */
        $return = '<a href="'.home_url().'/?author='.$comment_ID.'">'.$author.'</a>';
    }

    return $return;
}

Can I plug in some line/piece of code to direct it to the bbPress profile instead? If so, what piece?

Wordpress & bbPress are latest versions – website is http://www.novasev.com
Appreciate the feedback.
