One space or two?

I am a die hard "two-spacer" a.k.a. person who puts two spaces after every sentence. I am noticing that even though I put two spaces after every period, the blog grammer policeman removes one of them! Argh. Apparently, upon further research, we don't need to use two spaces anymore...I will spare you all the details. Oh well, I will proceed with my two spaces, even though you won't see them.
