Project Euler

Hey /prog/, I know I'm a little late to the party, but I was wondering how many problems you've solved thus far.
Other discussion regarding Project Euler is also welcome!

Problem 12
What is the value of the first triangle number to have over five hundred divisors?
In[12]:= For[i = 1, DivisorSigma[0, i*(i + 1)/2] < 500, i++]; i*(i + 1)/2
Out[12]= 76576500
