Yes, and I already responded to your original mail on this on Oct. 31th,
for some reason my mail client drops you from the CC, when I do a reply-to-all
to one of your mails (I've added you manually this time).

My replies did go to simple-fb at vger.kernel.org .I'll forward my 2 mails on this
to you.
