Why can't I submit my questions to YA anymore? Or give thumbs up? Wont let me, there's no submit button.?

This is very annoying. I type out my answer in full, then there's no way to send / submit it. Similarly, if I try to give a thumbs up (or down, I guess - I don't use them very often) to another person, it won't let me click on the icon. What's going on?

I mainly look at the Travel- Australia section. Is this problem just in our section, or other sections too?
