I for one would be quite happy for the odd interloper to appear if only to resume the previous anonimity. All the BACE forum needs at the moment is some tumbleweed to complete the picture.
Whilst it is fine for BOSD to reveal his identity this doesn't really tackle peoples desire to lurk in the shadows and not be found out. And the anonimity is what enables people to make astoundingly and unwarrantedly savage personal attacks, which, let's face it, is partly the reason we checkout pprune in the first place (joke).
