Sharing options in @MythOS include:

@Public Memos are visible by anyone with the link, appear in the Memo Feed and Search queries, and may appear in search engine results.
@Unlisted Memos are visible by anyone with the link, appear in the Memo Feed and Search queries, but are not indexed by search engines.
@Hidden Memos (coming soon) are like Unlisted Memos wherein anyone with the link can view and are not indexed by search engines, but different in that they do not appear in your @Memo Feed or any @Search.
@Private Memos are only visible by the memo creator and collaborators they have invited.
