I check and this guy has posted this and only other one time back in August. What was our policy on vendors? They contribute to the board first and then if they do they can be considered a friendly vendor?
I'd consider sending this e-mail to him:
"You've posted twice in the past year and on both occasions it's to sell your wares. Although we allow that in some special circumstances--it's only for those vendors that also contribute technically and informationally to the forum.
If you're going to just post links to sales--please refrain.
If you want to become a regular contributor to the community first, then please do. "
