I think if it is something that directly relates to how cs4 interacts with LR, then that's fine. Otherwise, I'm with Scott, also, with respect.
And it does seem to take a while to get used to forums. But this is the nicest one I've seen. No ya-ya'ing back and forth at each other and very knowledgeable "gurus" who go above and beyond to help.
Oh yeah, if you'll put your equipment info into a signature ( see mine and Scott's) then people will be better able to answer questions you might have. This is done by clicking on the user cp up at the top left of the forum. And welcome!
