You need to 'urlencode' the plus sign, as it is a special character that is used to describe a space in a urlencoded string. Essentially it is a way of escaping characters. Pretty much is is the percent sign followed by two hexadecimal digits which form the value of the octet of the character you are trying to display. + = %2B , = %2C & = %26 so your url should be http://whatever.com/taf.php?ntitle=Any+title&theurl=any%2Burl etc. For additional information, please take a look at RFC1738 which describes this process. Very simple procedure. PHP, incidentally will automatically 'unescapes' these characters. Cheers, -k
