Sending my scores?

I took the March 2015 SAT. When I check my scores on collegeboard.com, it says:

“Don’t forget to use your registration score report credits: You have until May 11, 2015 to take advantage of your four free score report credits.”

Does this mean I can send my scores for free to four colleges right now? Do I need to do this now? I thought that I don’t send scores until I start applying in the fall.
