[urgent] SC Review/Feedback request - Call for Papers XLIFF Symposium

Hi David and Yves and SC members,  I tend to agree with Yves on this. I've submitted quite a few papers over the years, and cannot remember ever needing to a third party broker to submit.  David, what advantages does the EasyChair method bring?
Thanks,  Bryan Ps. I think the two of us signing the call for papers is fine.
