I met my BF over 4 years ago on match.com. Some tips I can give about online dating is:
1. Always meet during daylight hours in a public place.
2. Always make sure someone knows where you are.
3. Have someone call you so far into the date so you can have a way out if you are not liking it or are uncomfortable. My friends also did this just to make sure I was okay. So I always told my date I HAD to answer the phone. If I didn't they'd sent out the search party for me.

Of course my first date with current BF was at 3pm and we ended up going up to Tahoe and spending the night in his condo. BUT he never even kissed me.
