Free resources I wish I had found sooner

I found a few free services in Oklahoma City that I did not know about. I have read a lot of threads here and could not find my exact situation. The library had résumé help and free computer time. What else is out there?

Call 211 to hear about local help with food, rent and utilities. It is free and open at all hours.

I found free tax help through a community volunteer programme. It saved me a fee.
