Check out Math Overflow, they are posting questions relevant to the research of the Tetration Forum's users.

I am trying to track relevant questions on my Math Overflow favorites.

f(f(x))=exp(x)-1 and other functions “just in the middle” between linear and exponential.

What’s a natural candidate for an analytic function that interpolates the tower function?

solving f(f(x))=g(x)
