A FB tip for entourage.....
Set up a new page that you're just going to use for events....a club night, random fun, socialising. Give it a name and begin by adding friends / girls you already know who'd be up for it. Add photos.
When you close girls using FB (short set, big groups etc) do a "party close" and tell them that you put together social events and you'll add her to the list. She can add her friends too.
Be Mr Sociable for a few months. Invite every fun, outgoing girl you meet, not just the HB10s. Very quickly you can get 50-100 people.
Now the fun begins....organise an event (club, bowling, river, bikes, shisha, film) and get as many people out as possible.
By simple probability, you're going to get laid using this FB entourage if you put the work in. It's something I do on the side and it's a great excuse to get out there and do more than just cold approaching. Hope that helps.
