To Speak Or Not To Speak

I have received an acceptance letter to present in the ICE conference. However, I will be on a business trip abroad and will not be able to present this year.

We are pleased to inform you that your abstract submission has been accepted for presentation at the 17th International Conference in Education (ICE2012), which will be held at Universiti Brunei Darussalam from 21 to 24, May 2012.

I have attached the official letter with this email.  You will receive the original letter by mail. Congratulations again on the acceptance of your abstract submission.
