Basically i need help on the whole process, ive read the sidebars but they haven't helped. I want advice on how to approach; I find it ok to go up to girls I kind of know and dance with them but then I dont know how to converse, im pretty useless, if a girl doesn't make an effort then I wont really know what to talk about.

So I need help on

1.Approaching random people 2.get a conversation going 3. keep the conversation going

Thanks guys/ girls, also all general advice would help :)
