Every speaker at the Users conference has a 20% discount code for friends and relatives who want to attend the UC2008.
Would you like to attend the UC, and save 20%? Send me a message! (my_first_name AT mysql DOT com).
If you don't know me, but you know another speaker, ask him or her for the discount code! And then, when you register for the conference, enter the discount code in the registration form.
Notice that I disabled comments to this post, so nobody will be tempted to ask for the code here. If you need the discount code, don't post comments. Send an email!
