Know somebody worth meeting?
Put them forward. We write to them once, say it came from you, and quote what you wrote. They decide from there, and if they are not interested they never hear from us again.
What happens to them
A matchmaker introduces them to one person at a time, by email, and they decide for themselves. Getting in takes two friends who will say something about them, which is the whole review. What you write here is one of the two, so the friend you put forward only has to ask one person of their own.
