I published with them a few years ago. I sent my article and did not hear back so I emailed them and they told me it was accepted. When I emailed them again to ask them when it was going to come out they sent me a copy of the volume where it was published. So it was a good experience because it was fast and easy, but they can improve their communication with the contributors. That was a few years ago, maybe that has changed for the better.
