I'm another user who has bookmarked SS64, and often link to it in answers that I post here in Super User and Stack Overflow. Thank you for a most excellent resource.

As indicated in the comments to Deltik's answer, I wasn't questioning the subsequent conflict with the edit from high-rep user LotPings; it was PeterH's rejection vote - which I read as not a vote to reject, but as a done deal; the edit was not going to be approved - that I was questioning. I have no problem with the rejection-by-conflicting-edit.

Yes; I believe I noted the conflict with subsequent by high-rep user LotPings in the question; I'm not questioning that - my question was specifically with respect to the PeterH rejection. That was phrased not as a 'voted to reject', but as though it were a done deal, and that's why I was questioning it.

Some communities have a flag reason for 'belongs on another site', and you can tell the mods which site. If a particular site doesn't, or if the appropriate site isn't listed, flag for generic moderator attention, and indicate that you believe the question should be migrated, and to which site.

And thus answered the question as to how I should have flagged it, had I been less uncertain.

@Ramhound - The querent was sufficiently well-versed on the subject of computers to have earned at least 262 rep on SU (he had 363 when I saw the question). No, a question being "elementary" doesn't inherently make it a bad question, but one can certainly note that a combination of factors makes the whole thing seem "off". Or perhaps I'm just overly sensitive to the possibility of trolls, after participating in this (now deleted) StackOverflow question

@djsmiley2k - It's certainly a VLQ, but it's on a topic that's just so elementary that I can't seriously believe that the querent really doesn't understand the concept even after (allegedly) doing research; the 'gut feeling' said to me that he was looking for responses that he could use as an excuse for abusive behavior or some such.

@DavidPostill - yes, I noticed that, almost before I was done posting this question.
