##Voting
Online voting/polling tools such as Framadate or Doodle can help in scheduling an event or in making a regular poll like "what colors should we choose for the logo?". Usually, the participant will have the yes/no/maybe options for each propositions. Depending on the options, they can change their choices afterward, modify the answers from others or none of these. When scheduling an event, there can be the option to synchronize the best choices with calendar applications. To use these tools, the creator of the poll must give an email address; but then, the participants can participate with just a pseudonym.
##Anonymous voting
The Technische Universität Dresden offers a fully anonymous voting/polling tool called dudle where the creator of the poll do not need to provide an email at all. They also offer a privacy-enhanced version of it. Depending on the chosen options at creation, it is possible to give the permission to every participants to even modify the different choices to be voted (e.g. adding more dates in a event scheduling).
##Brainstorming, collaborative wall
With Dotstorming users can add notes (with text and links) or images on a wall. After which, they can vote to their favorite ones. Depending on the options, they can have one or multiple votes. There is also a little chat tool where the users can discuss. This tool is power full for brainstorming, collecting ideas and making choices. To use it, the one that create the wall has to make an account. All the other users can then collaborate using just a pseudonym.
Flinga offers two collaborative tools: a wall and a whiteboard. The wall could be used to collect students’ comments, questions and answers quickly and easily for all to see. The users can vote for their favorite questions/comments. The elements can be sorted chronologically (or reverse) or based on the number of likes.
The Flinga whiteboard is a more versatile tool where the users can place the element into space, link elements together (approaching a mind map), draw, etc. Depending on the permissions set by the owner, users can modify each other posts or only their own or none. Both of Flinga tools can be used from mobile phones and tablets and the wall/whiteboard owner can easily show a QR code for quick access allowing a nice collaboration even in a computer-less classroom. With both tools, one user has to create an account to create a wall or a whiteboard; then all the others participants can collaborate anonymously.
##Anonymous brainstorming, collaborative wall
As part of the Knork EU project, we described our experience with tools such as TodaysMeet or Padlet or tricider.
With TodaysMeet, somebody has to create a wall with a possible time to live and share its web-address, then anybody can write messages limited to 140 characters to the wall. The messages appear on the wall in reversed chronological order. This tool is a good choice at the beginning of a lecture to ask question to students (e.g. about prior knowledge) and to give everyone an opportunity to answer, compared to a "classic" aloud question where usually only one or two student would answer.
With Padlet, a user creates a virtual wall and opens it for others (four levels of visibility from private to totally open) who can add "post-it notes" like texts, images, links, etc. without any login. Each users can then move and organize the notes. That tool can be used for example to collect ideas and opinions.
With tricider a user create a wall by asking a question and then share the link to it. Then everyone can write answers, comment and give their opinions and vote for them. We had positive experiences on using this tool like: for learners to argue better, for creating ideas, for discussing about content, etc.
I listed these tools as anonymous since it is possible to use them without creating an account. However, Paldlet and tricider do use many tracking scripts. I would recommend to use some browser add-ons such as NoScript prior to using these tools.
