I had trouble at first with the Rush application too. Choose the FreeText tool. Then drag the cursor on the actual application to form a box in the region where you want to add the text. Then type your text. Choose the hand tool and right-click the text area to bring up properties. Make sure the thickness is at 0 pt, the fill color is white, and the border color is black. With the hand tool you can click and drag the region around, or resize the box.
Same here-- no problem with the PDF. But I did notice that the SLU typo was on the PDF, Word, and paper copy that I got from them. I know this isn't a big deal (it says "have you appled to SLU previously"), but it's just really funny to me.
