Hello,
as an site administrator I would to like to be able to manage who is generally allowed to publish (own) surveys on the index page showing the publicly available surveys.
It there a setting for that available in LS or is this functionality provided by a plug-in?
Thank you,
Robert.

Not in core and not by know plugins.
