I don't think anyone minds, as long as you're honest about it. Unless they've slapped a copyright on it and have a pack of lawyers they're not afraid to use.
It's a nice puzzle. Though I haven't seen a way to do it without a lot of trial and error (which, admittedly, I left mostly to the computer).

I was thinking about the flagging other forums that might steal away our active members.
That said, that one didn't really grab my attention for long- there were a few nice questions- and it didn't seem hugely ative either.
Like you, I've still not foudn an elegant way of cracking it- but I'm getting there.
Another interesting link...
I feel like a small part of my brain just leaked out.

The EASY aren’t terribly difficult, the two hard were exactly that.
