No problem Tony - so when she helps, tell her to look for an "Attachments" button - it's one of the 4 buttons on the bottom of the type-in message area when you are writing a forum post, here:





When you push that button, an "Attachments" dialog will pop up - you'll need to do 2 steps to make the attachment, first push the "browse" button and then you will be able to pick which file you want to send:





Then after that is filled in, push the "Upload" button to actually send the file to the forum:





You can then close the attachments pop up once you have finished that upload.

After you have done that then write your message and push the "Post" button to send the message, and the file will be included as a link at the bottom of your message.
