Some of our customers will have noticed the text editor has changed in RedStar Energy (Dec 2009), and the majority of features are the same as with the old editor, but one or two things have changed, such as uploading a word document or PDF.  You can still do this, but the process is slightly different:

1. Edit your page and go into the HTML view
2. Click on the link icon:
3. Click on browse server
4. You can now either select an existing file from the server, or towards the bottom of the popup window, you will see the option to upload a new file
