> Somewhat in relation to [[ https://wikitech.wikimedia.org/wiki/Talk:Volunteer_NDA | this thread ]], I feel that Legalpad should allow three kind of permissions: read, sign and edit. Actually, for example anyone willing to read `L2` (https://phabricator.wikimedia.org/L2) to know what they'd be agreeing to in advance has to be a member of #wmf-nda-requests. Problem is that if we open `L2` to anyone, then anyone can also sign it and I feel that's the reason why the document visibility is restricted, to avoid unwanted signatures. If a "read but can't do anything else" permission existed, that wouldn't be a problem and documents not containing any private information could just be displayed to the public avoiding unwanted signatures. Thanks.
