function browserCh()
{
     $a = $_SERVER['HTTP_USER_AGENT'];
     $IE = ((eregi("MSIE",$a) || eregi("Microsoft",$a)))==1; 

     if($IE)
        return 'Bad Browser!';
}

I got a laugh at some of the responses.. :)

@honging : daynah, i prefer: <style type="text/css">* html body { display: none; }</style> ;)

@j_holtslander: @daynah that was kinda hot. LOL.

@robflynn43: @daynah Haha, browserCh() made me happy. You win a high five, redeemable any time you see me. =)

@ialexs@daynah :D (re: bad browser)

To install it, just download this file, upload it to your /wp-content/plugins/ directory. Then activate it in the Admin control panel.

Now in your templates, add this to your sidebar:

The if statement just says, if this function is available (if the theme is activated), then print the list of themes. Of course, you may customize the output however you want. There’s a little bit of PHP coding, but nothing to be too scared about. :)
