anyone else having trouble posting in the comments? Where is the submit button?

Many of us are having that problem. There is a periodic glitch. Try refreshing the page push f5 to do that and try this, push Control+ or Control-. also, if you're getting a lower pop up asking if you want to show all content click that then enter your answer in the box and the blue submit button will be there.

Didn't quite work for me although others seem to agree. Yahoo is terrible and often does things to infuriate people. Makes little sense. I wonder why a competitor has not crept in.

Yep ! That's the way it works... Thanks Riki..
