We would like to add a note on the website contact page that we can be reached by phone or in person in the board room on weekdays between 12:15 and 13:30 (or more often if you are lucky). Maybe you can figure out a nice way of mentioning this, otherwise we'll think with you ;)

### Why?
So people know when to reach us

### Current implementation
There is no note on the contactpage of the site

### Desired implementation
There is a note on the contactpage of the site
