<p>insticc_conferences,
A conference subject is something like <a href="http://www.freebase.com/view/guid/9202a8c04000641f800000000a7e4dea">Software</a>.  Conference subjects should not be conflated- conference subjects are a single subject and you can add multiple conference subjects to a conference.  This is not a proper topic and it could possibly be construed as spam.  I have updated your topic accordingly, and you are free to add more (proper) conference subjects, but I have marked this one for delete.</p>
