well, me :)
There's a math group on A/N.
well do something then.
If you have G+ there are some really interesting math groups there and they are very active
What training do you have?
I posted a bunch of puzzles in the math group, do you like any of them?
The puzzles can be understood without a lot of math background.
As for my background, it's similar to a grad student who's taken about a year of graduate math classes. I took a couple years of abstract algebra at Caltech, algebraic topology, etc. - and I've done a lot of reading on my own in Lang's Algebra, multivariable complex analysis, some number theory, some algebraic geometry, p-adic analysis.
