Yes hard work any 18 hours a day at the least, i opened my other website 2 weeks ago whilst developing the site with a friend etc etc and now over 100 members, cant say i tried hard but i kept it relevant anf targeted. I have few friends joined up (a small handful) but from hard work and niche targeting mine is off to a good start. do lots of link exchanges write articles use large social network, im telling you it works. Good luck
