You can now Edit a document file name after it has been uploaded to HowNow Online.

Search for the document, click on the More Action button and select the Settings option.

The Profile window will appear.  Make your changes to the title listed in the "Filename" field and then click on the "Save" button.  This will update the filename of the document.

Some settings cannot be changed if your user-id does not have permission to do so.
