Thanks for taking the trouble to point the way. As it happens, I had already stumbled across the learning log area and even went so far as to write the first instalment of the awkwardly titled Mark's Log of Learning. Why the forum algorithm objected that Mark’s Learning Log, as I originally tried to call it, was too similar to other log names, I do not know. Actually, on second thoughts, it wouldn’t surprise me if that title had already been used by another Mark.
