The organizer presents several options that you can vote for (in the case of a group meeting poll or survey) or select (in the case of a 1:1 meeting). You select "yes" by voting for the option, and "no" by not selecting it. Simply enter your name into the name field at the bottom of the table and check all the options for which you are available or agree to. Then click "Send". If you cannot make it on any of the dates/times or you would like to say "no" to all options, do not select anything, and click "Send - cannot attend"
