Dear Ruby,
You can only upload files if you are permitted by the group owner to do so.
what you can do is to post the concerned file as attachment along with your message to the group or to the group owner with request to upload the same. or if you want to see the file on the page itself you send it to me ( at
mail...@gmail.com) i will post it and will palce its link on the page so that the members visiting the page can also see the draft agreement.
regards
