I suddenly realized I have forgotten to say thanks to Jennifer Evans, who has helped me do an extra round of proofing of the English part of my company web site. It was originally written by an English speaking person, later on updated by me, and now yet again proofed by another English speaking person. I am very grateful for the small, but important, improvements made by her. This goes to show that a text cannot be improved enough, there are always some details that can be polished. Thanks, Jennifer!
