First of all, I was not satisfied by the performance of the event organizer. Firstly, they changed the venue last minute. Secondly, many members did not receive confirmation letter. Then, the event was delayed till 3:00pm instead of starting at 2:00pm on that day.
I did not receive the confirmation letter as well, and the organizer had no records of me! Anyway, they still let me in. Otherwise, you would have been reading my complains here. :P
