When new members sign up for your space Cobot can ask them a few questions on your behalf. A lot of spaces use this to ask for things like profession, social media accounts or to just get to know their prospective members better.
Until today all questions had to be answered in a text field. Now we are adding drop-downs and checkboxes. For example if you are asking which neighborhood someone is coming from instead of them having to enter it by hand you can give them a drop-down with all the neighborhoods. Not only does this make it faster to fill out the survey, it also makes it easier for you when analyzing the results as the data will be more accurate.
To set up your own survey go to Setup -> Member Questions.
