Beware of the owner of this site - a guy calling himself 'Philipp' whose ego is bigger than the Austria he lives in.
Quite at random he will hide your profile from all other users, whilst you yourself will continue to be able to access it and believe mistakenly that others can see it. You will be wasting your time.
I have heard this from many disillusioned members of the site.
Recommendation: More likelihood of meeting with others by sealing yourself in a locked room.
