What I should do to get more Responses

I don't know what you mean by trying many topics, but since your profile shows that you've only started two discussions, and the one point means that you've only responded to someone else's discussion once, you've hardly participated at all on mylot. You've been here a month and haven't done anything, so why do you expect responses?

I've found that if you have more friends on this website, than you get more responses. A lot of people check discussions that their friends post first and reply to them over others. Thats what I do.
