Not sure what you mean by "...allowed one post on this board...", since you posted twice today on this board (Q&A), but I think you should discuss with Admin via PM.
"...After my last suspension on this board I have not made but 3 or 4 post and not one had any derogatory or vulgar language towards anyone and it was all on topic. I'm confused why I'm only being allowed one post on this board...."
"It is easier to fool someone, than to convince them they have been fooled."
For those that don't get it, it means that people need to be more careful, and do good due diligence...
