Survey plugin provides survey features such as:

 - multiple questions,  - extended set of available question types (notation, free text, multiple choices, etc.)  - nice results views, and results filtering, per question and per responder  - CSV results export It is intended to admins and optionally group admins rather than to simple members.

The plugin was originally forked from Poll plugin 1.10.2. Some of the implementation ideas also come from knowledge_database plugin from Facyla, with insights from Evan Winslow proposal at https://github.com/Elgg/Elgg/issues/6808

This plugin has a different aim than "poll", and is not backward-compatible. In fact, both plugin can be enabled and used at the same time to provide simple polls and more complex surveys.
