Hey guys

I am now starting to get pretty good at guitar and i would like to start recording myself. The problem about this is that i dont have any programs that will allow me to record myself. I do have a microphone but i cant record myself. So if any of you guys no some program that will allow me to record myself playing i would really appreciate it if you tell me about it. Also i am low on cash so i would prefer if it is free.

thanks alot guys
