How long have you been around, andout? Sadly, this really isn't unusual. I don't know if you saw what happened on another thread earlier?
Gustix posted a similar question, something that I believed - and still believe - he knew (although apparently, he didn't know who went by the nickname "Briggo", or recognised him). I answered in a friendly and informal manner (using nicknames and first names) - as I thought it was just a little test to see if anyone else knew - and he blew a basket, and accused me of trying to "eff him up"!
Like you, I don't know what he is trying to achieve when he posts stuff he knows, but acts like he doesn't...
