mixin let you share your agenda with your friends in a real simple way. Just specify what you are going to do naturally and let your friend get in touch with you to do things together more often.
But sometimes, you want to do something with your friends, but you don’t know precisely where and when. For that purpose there is a type of activity called a proposition. The syntax to create a proposition is the same as the one to create a plan with one exception. You need to add a question mark at the end of your post to create a proposition. The proposition allows you to specify multiple choices.
For example, you want to lunch with friends but don’t know when and where, just enter the choices separated by semicolon.
Example

Once a proposition is created you can decide if you want to leave the different choices (what, where of when) open or not. Just click on the links next to the choices to open or close them. By default the choices are open.

If you want to invite people to discuss this proposition, click the “invite people to this event” button. You can either select particular friends on the service or invite new friends by entering their email addresses separated by commas.
When your friends receive an email there is link to the detail page. On this page, your friends can vote or make suggestions if you left the choices opened. And each time something is happening on this proposition (vote, suggestion) or posted to the proposition (comment, media) the users invited to the proposition are notified via their preferred communication channel.

And once the votes are over, the person who created it can transform the proposition into a plan. The administrator of the activity needs to make some of the choices final.

And make it final
