Tweety Explores Google Docs - Thing 16

Since I am not a part of RESA's 23 things, I am unable to work with the spread sheet they provided. I did explore Google docs on my own and I see great potential here. How many times have we tried to update rosters, forms, documents only to not have all the participants available? If we have everyone's email, they can update their information online in the original document! I shared some test data with Priest administrative cabinet and it was only for their eyes. No one else had access. It was in graph form. I am interested in whether changes can be made to that since only spreadsheets, presentations,and documents were mentioned. The possibilities for collaboration is thought-provoking.
