MySQL Speakers and Presenters at LinkedIn

There is a Linked In group I created some time ago but forgot to advertise that is for MySQL Speakers and Presenters.

If you a speaker or presenter of MySQL content, confirm your registration here .
You will need to have a reference to a website confirming you have been a speaker at a MySQL Event such as a User Conference, MySQL Camp or Local MySQL Users Group.
