It has tons of small but useful tips:
- host it Monday or Tuesday from 7-9pm. People are usually free those nights and make sure it ends at 9pm for the folks who have to wake up early
- don't send an evite with "0 of 60 guest have responded". Start by having your core group accept and then send the invite directly to each new person
- have name tags. but make sure YOU fill out the name tags or you will have "Batman" and "Superman" at your party
- introduce people and have "get to know you games"
Now, I'm sure someone will say "this is so formulaic and doesn't feel natural!". That's kind of the point. You need to give folks some structure to be able to interact. The name tags for example remove the "oh, I met this person before but I can't remember their name so I just won't talk to them" etc.
