I went thorough all the people in the "People Near You" list or whatever is on the right when you look at your profile. I copied all their emails and sent one to everyone saying we should meet one sunday, and we did. All of a sudden I founded a gang. Crazy. And now they put up with my e-mails, and the forums and blog and other stuff we have/do.
And now they spend all their money on mopeds, and probably secretly curse me for spreading this addiction.
So, do what I did.
