My First Real Venture into Online Dating

I did it. I signed up for an online dating service today and paid the fee for the first month. There sure are a lot of single mothers on there. Should I be opposed to going out with girls with children? In the past, I have generally avoided it because well... instant family. Not sure if I am ready for that. I sent a couple messages to a few girls. I received a few messages from some girls that I have zero interest in dating. Thus far, no response from any girls that I might have real interest in. If any of you want to offer specific help with online dating (such as suggestions of which pictures to post or what to write about myself), I would greatly appreciate it. Just let me know and I will show you my profile. But for now, wish me luck.
