Nevermind, got it to load the plugin... but, it installs plugins to /usr/plugin ... is that correct? would something like ~/.alkquotes/plugins be more appropriate? <br><br><div class="gmail_quote">On Sun, Jun 27, 2010 at 5:23 PM, Brian Cappello <span dir="ltr"><<a href="mailto:briancappello@gmail.com">briancappello@gmail.com</a>></span> wrote:<br>
