Dear Colleagues,
Based on the guideline outlined on the File "Korean SIG Listserv Rules"
on our ataKorean yahoo site please do not post any discussion of rates.
It could be considered as a 'price fixing' activity.
Below is an excerpt from the guideline:

Legal Rules Without Exception
1. The ataKorean listserv should be considered by participants to be an
online meeting subject to the same anti-trust guidelines that prevail
at association meetings. Therefore, * Do not post material that
includes discussions of rates, and matters related thereto, as
specified in ATA's Policy Statement of March 25, 1990 (see
http://www.atanet.org/bin/view.fpl/13626.html)
