Senior, nope - Jake had posted a thread in here to say he'd posted his KX500 forks for sale in the for sale forum.
At a guess, one of the moderators deleted it as if everyone posted a link to their for sale thread, what would be the point of even looking in the for sale forum? (or even having the forum to start with).
That's my theory on it, in any case. As for why it got deleted without a note, I thought they might have dropped you a line, but then again, if they did that all the time, they'd have no time to check out everything they do (and they do all have real jobs).
