Using Slooh telescopes and “block” booking

Does anyone have a contact email for an exec at Slooh?

I use their telescopes regularly but recently there has been a lot of repeated booking for the moon taking up a lot of observing time. None of these users seems to be aware of the ‘Join mission” option which would avoid taking up observing slots. Nearly all bookings from 8pm to 23:45 are taken up with ‘Waxing Gibbous moon’. Joining an existing observing slot would be more efficient.

Yet I cannot find a contact point to make a suggestion to promote ‘Join’ option.
