Hello FV world! Can anyone suggest a great and free software tool that will allow me to submit blogs and articles all at one time to tons of sites?

I have been doing some research and seem to be coming up with tons of course, however, I typically like to go with what others know and trust!

Please advise and I greatly appreciate your help as I am preparing for back surgery on Monday and need to get this in place ASAP!

Make it an outstanding and beautiful day FV world!!!
