We arranged this so that it would be entirely within each user's control. SpiderOak never publishes the names to share rooms, so someone would have to know the name or URL to go there. Also, all share rooms use SSL (https) so they won't show up in proxy server logs and things like that (although they do show up in browser history).
So, if you want a search engine to index a SpiderOak share room, you just need to link to that share room on a public website somewhere. Then the search engine will know of its existence, and be able to craw/index it. If you never post the share room publicly, it will remain private.
Keep in mind, though, that your share room may be indexed inadvertently through seemingly private sharing. If you give a link to your share room to a friend, and he innocently puts that link on his blog, twitter, myspace, or similar, it will get indexed whether you like it or not. In the future we will provide more fine-grained controls over search engine indexing.
Embedding a share room login box on your website or blog is easy. Just copy the HTML code below and paste it into your website.
Note: If you only want to link to a specific share room, the code below is not necessary. Simply open the share room you want to link to by using the share login form on spideroak.com, and copy the URL shown in the address bar of your web browser. Paste this link into your blog or website just as you would link to any other website.
Example: <a href="https://spideroak.com/browse/share/ethan/test">My Thesis Papers</a>
SpiderOak stores your data using a nested series of encryption keys. This allows SpiderOak to make any specific folder or file public without exposing any of the other data you have backed up.
To edit a share, click on the name of the share and click 'Edit'. You are not able to change the RoomKey or the unique URL once a share has been created. If you would like to change the RoomKey, you must delete and recreate the share. To delete a ShareRoom, click on the name of the share and click 'Delete'. You cannot undelete a ShareRoom; if you delete a share by accident, you must create a new one.
To edit your Share ID, open the 'Account' window in your SpiderOak client, or, after logging into your account remotely via the My Login link at SpiderOak.com - choose the 'Account' tab on the SpiderOak website. Next to your current ShareID you will see an "Edit" button. Click this to reset your ShareID.
Unfortunately it is not possible for you to edit the "Name of Person Sharing" which appears at the top of this share. This will always by default display the first and last name you gave when signing up for the account. If you absolutely need to change this information, please contact SpiderOak support.
You can access your share room one of three ways. First, the unique URL generated when you created a share is a secure way to access your ShareRoom. SpiderOak uses https and other measures to ensure sharing is done in the most discreet and secure way.
You can share this URL with anyone at your discretion. The invitees will be able to see the name of the person sharing, the name of the share, the RoomKey (in the URL itself), and all files and folders in the share. Invitees DO NOT need to be SpiderOak users to view the contents of a ShareRoom Second, you and your guests may also access your ShareRooms by clicking the Share Login link at spideroak.com (https://spideroak.com/browse/login/share) and entering the ShareID and RoomKey for a specific share
Lastly, you can also access your share room from your SpiderOak account online. When you are logged in to your SpiderOak account online (see Accessing my Account online), you can click the 'Share' tab to see a list of all your current ShareRooms. Click on the name of the Share to view the ShareRoom.
Even though all your data is stored encrypted, you can carefully and selectively allow portions of your SpiderOak Network to be shared with family, friends, colleagues, or clients. You can create a ShareRoom by choosing any number of folders from several of your computers. A ShareRoom may be accessed as a unique web URL or by entering a user's ShareID and RoomKey on the SpiderOak homepage, easily allowing people you invite to view your documents, pictures, movies, and so on. As you make additions or edits to the folders within a ShareRoom (no matter what computer those changes are made on), the changes are automatically viewable to those who have access to the ShareRoom.
