Ok, I'm on the Board view. I scroll down. There is 5-6 physics forums, 5-6 mathematics forums but below only one for biology and chemistry. I assume that PF (as the name) was originally though for physics and math? Are there any plans to expand biology, chemistry etc. to own categories or is that only if and when they are more active? Might it be becuase that would kind of make PF deviate from its "Theme" (physics, mathematics)?
