I'm currently running a triple experiment:

• For the first time in my career I'm trying to organize a public workshop completely on my own. The topic is Advanced TDD and I'm very thrilled about the simulations and exercices I want to do there. The first run will be in German.
• I'm auctioning one of the seats for this workshop on ebay. Let's see how this turns out.
• Since I'm very eager to reach the minimum participation of 4 as soon as possible, I'll give a commission of 20 percent to anyone who'll send me a customer until 4 seats are taken. Just tell the interested person to refer to you when they contact me.

Update
The first auction ended at 401 EUR. So I started a second one which resulted in 512 EUR. Not bad I'd say..

Update 2
I'm sold out 6 weeks in advance.
