It was 29th September 2013, one Sunday afternoon, that a group of individuals interested in mathematics education gathered together for the first **WikiTalk** that proved to be the first of a growing number of seminars in mathematics education which is now approaching to 100! The rule was simple, if you have something to say, believing that it is worth sharing with the others, come and WikiTalk.

Wikiletter is the natural child of WikiTalk.

A **WikiLetter** is a short text of the maximum 2000 words that would be the tip of a research or a collection of related research. Something as naked as possible, presented in the way that we talk through our work with excitement. We just tell it in the most straightforward way possible what that is we are exited about; if we mention the work of someone else, it is more paraphrasing rather than quoting; we focus on just one thing and keep it simple trying to attract our audience, etc, etc.WikiLetters are exclusively written as WikiLetter and published in English and Farsi.
