I was trying to add a new message to the home page and somehow all the data on the left side of the page moved to the very bottom of the page leaving all the space above it blank. I don't know how to get it back to the top.
I need help!!!

The very first image in the announcement has this
style="margin-left: 120px;">
That is pushing the image over too far and thus pushes everything else down to match.

Remove that "style" and use "center" for the image instead.

Use source mode to find this if you don't know how it got that way. That's the upper left option in the Editor. After clicking, editor now shows the HTML on your page. Just delete that first to see what happens.

Click Source again to get back to visual view. Select the photo and then click on the "center" icon, 2nd row just past middle of alignment options.
