GGRRRR..

Blogger friends...I know I have posted this before...but why do none of my comments work on anyone's blogs.  It just keeps going back to that I need to sign in..even when I am signed in.  I believe someone said they had to stay signed out to post...but mine still won't post.  I'ts been so frustrating...and I've just stayed away from my blog world because of it!!!  Help!!!
