Translation of coalesce in German

Thanks for the message. I hope that your friend here in England will soon be feeling better. If you decide to come at another time, I would be very pleased to meet you here. You can sleep at my place.
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.
I'm fine, thanks. I'm sorry that I did not write back to you sooner. As you see I am very busy with my work. But I'll take the time to help you because I promised to do so. So let us start soon.
