From my gmail notification of subscribed threads:
You are subscribed to the thread “Darn it, Maxis!” by avabeth, there have been 2 posts to this thread, the last poster was harmless.
I’m not going to ressurect the ‘Doper names you like’ thread, but I’m mentally adding **harmless ** to that list. 
I’m cleaning the sprayed water off of my screen, which ended up there as the punchline dawned on me. It just struck me the right way 
If only it had been “mostly harmless”
I think we need a poster called “very dangerous”
Or Nibbled to death by ducks
Or The Nibbling Duck of Death :eek:
I always have the same reaction on a forum page when I’m looking at the “last post” column and I see “by gum.” Every. single. time. I say to myself “By gum!”
Just keeping with the theme of the OP. 
Hmm. That’s not what I get at all for email notices. I get:
"harmless has just replied to a thread you have subscribed to entitled - …‘the last poster was harmless’ (very Mundane & Pointless) - in the Mundane Pointless Stuff I Must Share (MPSIMS) forum of Straight Dope Message Board.
This thread is located at: … "
with a link to the thread. Not as funny that way.
I keep getting variations.
I use to get notified every time someone posted in a thread, which sucked because it would flood my inbox on a good thread.
Now I sometimes get notified, sometimes don’t, and sometimes it will notify me that the thread I’ve subscribed to has 15 new posts, the last being mine. :smack:
I just figure the hamsters haven’t anything better to do, or they are just a little off, if you know what I mean. 
As soon as I saw this thread I knew one of the first replies would be a Hitchhiker’s reference. I love the SDMB.
I have it set to update me once a day - maybe that’s why my message is different to yours, BiblioCat? 
Hrm, I wonder if it’s possible to change my name to ‘Nibbled to death by ducks’…?
Or ‘immediately set upon by peasants with pitchforks’. 
Well, in that case I call The Nibbling Duck of Death. 
I’m always happy to make the obligatory obvious jokes.
6,259 and counting…
Just kidding. For the record, I’m always happy to do the same.
I think someone should change their name to Nibbling Duck of Death. That is such a cool name.
Offhand, has anyone considered the username Nibbling Duck of Death? Just a thought.
WW: Um, it’s Duke.
Little Bill: Duck, I says!
Hmm, could be. Mine updates me immediately.
“Hey, I’ve got three arms!”
“I said ‘harmless’, not ‘armless’.”
