If you PM them and ask them to do it then yes. I'd imagine that if you posted here:
"If anyone knows where I can find this software in some form or another, please PM me if you do" then that's tactful enough.
The point is we don't want people publically using this forum to post warez links left right and centre. Hell, I'm mindful that allowing people to ask others tactfully - there'll be a host of new topics springing up asking for all kinds of software. That's not what we're about at all and to be honest I'd rather people looked for warez elsewhere - lord knows there are plenty of places for it.
