Although some functions will be taking place on Wednesday, 18 June, I suspect that you are looking towards the days that the bourse floor is open.

If however, you are interested in attending the Wednesday trade session, or the First Timers Session, or the Banquet and follow-on trade session, then you must pre-register and the deadline is 1 May. You can do it on-line here: http://www.ccgtcc.com/promo/preregister.php

Or via snail mail by visiting that same link, printing out the form and getting mailed ASAP.
