Translation of evaporate in German

I would rather like that you write through the messaging system on this site and not to my private email address. All the info is gathered here online and I would like to keep is this way. It is nothing personal.
I really value honest comments, and I am a believer that it is the only way that the social community system works, so as to know whom you can trust on both sides. Programmers did a great job if you were asking me.
Perhaps we are could meet sometime in person, not just via the Internet. Of course, we should still write each other a lot. I will get back to you once I am back in Cologne, and then give you know.
