I have some canned answers in Notepad++ for common questions.
If you use a canned answer, then it usually shuts down the thread.
If you use a canned answer, then it usually shuts down the thread. The op most likely will clear off, or maybe repost the query in another section. It prevents discussion by those who may be interested in teasing out the details. It may be better not to answer at all. It sort of reminds me of bidding on ebay - who gets in quickest, and increases their status.
It would be better, but maybe only for me, but probably not possible, if those short threads could be removed. A bot could do that, I guess.
I have some canned answers in Notepad++ for common questions. So instead of typing the answer over and over I just copy and paste. Also a canned read the stickies response.
