Yes, you are spot on in that the message you refer to was, shall we say, on the edge. I am aware of the terms and conditions. I wanted to make a serious point AND test the boundaries. Why? Because there doesn't seem to be any rhyme or reason about what messages are "censored" for want of a better term. That message, I expected, would have mysteriously disappeared like many others (for which there was no valid reason to censor). If it did offend you, and I suspect not, then my apologies.
As far as responding to messages I don't care how you address them, if they are put on a public forum, they are public. Even if someone said "PRIVATE MESSAGE TO LES" on the Forum, I would feel free to read it and respond to it.
For private messages there are other ways - Guest Book for starters if they are members of TP.
