With Azendoo you can evaluate an idea or get it validated by your coworkers.
Start a new message and click on the 'Add a poll' button. From there you can write down your message, and customise the answers your team members can choose from, up to 5 choices.
Select the appropriate subject(s) to share the message on and click on the 'Share' button to post the message and its poll.
The team members that have access to the subjects you posted the message on will see the message and the poll options in their activity timeline, and can share their opinion with you and the team.
Of course they can also post comments to the conversation.
