I'm trying to post a suggestion to the feedback website, and the "submit" button is grayed out and non-functional. The title and body of the text are both within the character limits, and I've selected a topic, so I don't know why it isn't letting me post.

It's not because I have a suggestion open already, is it? Surely we're allowed to have more than one suggestion up at a time. 

I can comment on things just fine, but I can't make a new post. I haven't tested if it's in all sections, because I'm sure me making random test posts wouldn't be appreciated.
