Ok, if you are viewing your calendar in list view, simply right click the Columns bar and choose "View Settings". You can also select View then View Settings from the ribbon.

Within the Advanced View Settings List, Select Columns. To add comments to the columns bar you will need to select the drop down and select available columns from "all Documents Fields". Comments will be in this list.

Hope this helps.

Thanks for the input everyone. But my girlfriend found the answer.

Spider Tech, you were mostly right. Good instructions, thanks. But, the field where you can type anything is NOT call "comments", it's called "message".

Once she created the column in the list view called message, everything I typed in that open area in the create events window showed up perfectly.
