recreational maths venue for amateur mathematicians does anyone know of a recreational maths venue which publishes, announces, or distributes mathematical results (at university level) which would be of interest to amateur mathematicians also ?
Thank you.
 A: The Best I know is G4G (Gathering for Gardner Foundation: http://gathering4gardner.org). From 2010, people around the world celebrate the birthday of Gardner and G4G somehow links all of them together. It is up to you at what level you celebrate it. We did it at our own university and students from all departments (science including mathematics, physics, chemistry, and social science) were involved. Just visit G4G and you get many useful ideas and you may share your own ideas.   
A: Recreational Mathematics Colloquium mentioned in the comments above : http://ludicum.org/ev/rm/13
A mixed bag of (possibly) relevant journals, some of them well-known:


*

*Convergence

*Forum Geometricorum

*Mathematical Intelligencer 

*Mathematics Magazine: 
MAA
JSTOR

*Plus
EDIT
And more, including a French one: 


*

*The Mathematical Gazette (UK).  

*l'Ouvert (not sure about its current status, the site appears not uptodate and somewhat broken)

A: Also two journals to mention here :


*

*The graduate journal of mathematics (The Graduate Journal of Mathematics is an electronic journal that publishes original work as well as expository work of general mathematical interest which add to the literature, have pedagogical value and help make more widely accessible significant mathematical ideas, constructions or theorems).

*Journal des élèves de l'ENS Lyon, (original work, expository work and recreational maths, but I don't know their current policy about people not studying at the ENS Lyon and wanting to submit there).
