Glad to hear that :)

Well, the two uses of "free" are not unrelated.
For instance, when checking the validity of an atomic formula in a  
free algebra, the free constants of the formula, if any, behave  
exactly like the free generators of the algebra.
But it is probably safer not to delve further into this now :)
