Viewing a document on MapleCloud means that you have downloaded it and can save it.
MapleCloud has different groups for controlling who has access to your document.
Any document that you upload to the public group can be downloaded and saved by anyone with Maple 14 or higher.
If you want to keep your document private, you can select "private" from the dropdown. This is a way to store your documents if you are working on more than one computer. You will have to log in to get your documents.
You can also create your own group if you just want to share your documents with a few people. You will have to approve their request to join your group.
Type "?cloud" in Maple for more information.
