Complete waste of time. Women think that all men are only looking for sex, however they don't take the serious guys seriously. Went on a few dates, needless to say the women I met were all unsure of what they wanted. If you're an attractive woman, expect tons of messages from men, if you're an attractive man, expect mesages from fattys and ugoes. Expect about 1 response for every 20 emails sent out, and out of those messages you get back, expect a short uninterested response.
Pros
