I've not seen anything recently either, like since the end of February. I just looked at the archives and the last message there is one I remember getting back then.
Seems like HO Steam really is a quiet list - 258 messages since the list started last year.
I'm wondering if the list wasn't down for a while - last week I requested a copy of the Bachmann Spectrum 2-8-0 disassembly/servicing instructions (my swapmeet loco came without them) . . . and my request didn't even come back to me.
