I suppose you don't know: typing all in caps is considered very rude (equivalent to shouting).

comment Using FindFit to fit $a\,b^t$: how to avoid introducing complex numbers?
the "[VeryThinSpace]" part makes me suspicious. CHeck your function and your data using FullForm to see if you realy are trying to fit to numerical data or if something went wrong with the import or the input of the function.

comment How to group the powers of one variable?
This is equivalent to assuming a and b being reals. According to the documentation, PowerExpand always assumes real numbers and integer exponents.

@jVincent Thanks! It seems like BoxData is the way to go. However, if use CreateNotebook[CellGroup[{CellPrint[..], ExpressionCell[...]}], the output of CellPrint appears in the parent notebook. Any idea on how to redirect it to the newly created one?

comment Subscripts in programatically generated section headers
That works, thank you. It is counter-intuitive though to convert a string to an expression before putting it into a section title - never would have thought of that.
