Leon,
Based only on the information you gave us, I would "do nothing." I read this board everyday and it is not obvious to me who you are talking about. It seems like this person gets under your skin and irks you. He might add nothing to this board, but that is true of a large percentage of our members (including me). Perhaps, that is why you have distanced yourself a little bit from Net54? Or, at least don't seem as involved. Don't let one "numskull" get under your skin, at the end of the day it is not worth it. Let it go, don't scoop to his level (personal level), and move on.
This philosophy guarantees a long life with a full head of hair as a bonus

Lovely Day...
