title: Checking Pligg CMS User Account for Login through Wordpress
body: <p>I am stuck trying to figure out a way of checking if a user is logged into one system (Pligg CMS) while on a Wordpress blog. The installation directories would look as follows:</p>
  
  <p>Pligg CMS install: www.mysite.com/</p>
  
  <p>Wordpress install: www.mysite.com/articles/</p>
  
  <p>I'm not sure if anybody knows about how Pligg or Wordpress works with user management and login details. I'm sure I could put the pieces together, I'm just having a very difficult time getting started. How can I pull information from Pligg's login session into the WP installation which will be inside a sub-directory? Is there a PHP class I could use, or is there a better way of approaching the problem which I'm not aware of?</p>
  
  <p>If there's anything confusing or strangely worded please let me know. I'll be happy to clarify any problems as I'd really love to solve this one!</p>
