You go girl
The only tip I have on on-line dating is keep yourself mysterious. Don't give out your whole life story. Talk about sports, weather, trips you've taken but keep your personal stuff to yourself. If I do meet them I also drive myself and have them take me to a nice place to eat

Have fun and don't stick to one.
I'm so happy your jumping in on that fostering. I would love to do that one day. I'm sure you will be a great foster mother. Lot's of kids deserve love and affection.
