Hi, I should say your script looks pretty good ;-). Sorry, I didn't have much time to _really_ study into it, but here's what I've found after a quick scan:

In your xqsend() subroutine, you have the following:

  if ($_[0]) {
    my $user_index = $_[0];
    $user = $xdccqueue[$user_index - 1]{user};
  } else {
    $user = $xdccqueue[0]{user};
    #IRC::print("$CX Checking for$CB $user$CX from queue... $CO\n");

  }

First, you don't need to initialize the $user_index variable to simply store the value of the first subroutine argument, considering that the only place you use it is in the line immediately below its initialization.
Therefore, I'd propose to exchange your if/else block for this:

  
  $user = $xdccqueue[(($_[0] || 1) - 1)]{user};

Or, better yet, just use this:

  
  $user = $xdccqueue[$_[0]]{user};
[download]

since

(qw(foo bar))[$_[0]]
[download]

would still yield 'foo' when @_ is empty (therefore, $_[0] is undef).

• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
