It would be better if there was a link on every page - maybe somewhere at the bottom.
Part of the problem is that it is well hidden and you have go looking for it when you need it.
What I see is only 2 of the 3 ways to "contact" ...
Clicking the "S)-inside-the-circle" has no effect.
I tried it on Windows 7 & 8 & 10. No change.
