Not currently but I've been registering my recordings on etree to get the SHN ID as I upload to LMA. I'm not certain though I believe they eventually end up on etree, however, I'm not specifically uploading them to etree.
Not sure why you asked, but if you use Firefox as your browser there is a plug-in available called "down them all" which makes it easier to grab all the flacs from LMA.
On another; it was late when I uploaded after a long day and I accidentally put a identifier redundancy on this show. I'm looking into having it adjusted to eliminate the redundancy which will break the link I posted but I'll update the link if it does get changed.
