Visichat 2.5.6 signup fix

[admin]

There was a small bug with signup page on the email validation function, so simply modify following lines to fix it.

Scripts/signup.php line 54:

Find:

if($email == "" || preg_match('/^([a-z0-9])(([-a-z0-9._])*([a-z0-9]))*\@([a-z0-9])*(\.([a-z0-9])([-a-z0-9_-])([a-z0-9])+)*$/i',$email) ==0){
    die("&result=invalid_email&load=ok");
}

Replace with:

if($email == "" || preg_match('/^[A-Z0-9_-][A-Z0-9._-]*@([A-Z0-9][A-Z0-9-]*\.)+[A-Z]{2,6}$/i',$email) ==0){
    die("&result=invalid_email&load=ok");
}
