Man, I came in here thinking it was going to be filled with good intentions

As for making attachments, yes, you should be able to do so by clicking in the bottom right corner on the "Go Advanced" button at which point a Paper clip icon will appear above where you enter your text. click on the Paper clip and a box will pop up for you to make your attachment.

I'm not sure why that doesn't show up until the "Go Advanced" button is hit but that's where it is for what it's worth.

Despite my initial silliness I hope that helps.
