@amWhy not really, but I check in at times.

@quid I'll send off a quick hello, then! :-)

@amWhy thanks, see you!

Math.SE mod, or SE community manageer: Is this username okay?: here I mean I know almost anything goes on SE, but this username could be taken pretty destructively.

@amWhy I'm not a mod nor a CM, but FWIW it seems to be a literary reference : en.wikipedia.org/wiki/Ender_Wiggin

@ArnaudD. Thanks, @ArnaudD. That helps. I had never met that reference.

@amWhy I don't really know it myself, but Google helped :)

@ArnaudD. Yes, you could have (deservedly to me) replied "Let me Google that for you". I just had a gut-wrenching reaction, I guess, to "xenocide" = "xeno-" (different/strange) + "-cide" (murder), that threw me off!
