If you have a general question regarding the use of Conference Manager, you can often find the answers here in our FAQ.
Can I send out a questionnaire without inviting people?
You have the option to send a question/evaluation schedule to all the people, you have added to the system. You can just add people to the invitation list and still send questionnaires to them. By doing so, you have the opportunity to receive ideas from potential participants to your event and adapt it to their wishes, even before the event takes place.
How do I send a questionnaire to only some of my participants?
If you want to send a questionnaire to a particular group or specific selected participants, you can click on the 2nd tab "Participants" where it is possible to search from the listed filters.
