I will of course require the code to be of reasonable quality before I = accept it, but I'm also happy to give helpful review comments and guidance. So don't wait for permission, if you want to try implementing something= , just do it. Equally if there is something that I particularly want done I won't wai= t for ever for someone else who says they are working on it. But RAID10 resh= ape is a long way from the top of my list.
