Now, THIS reply is a double-post because my reply above is the last post in this thread, and THIS reply is less than 24hours after the above.
If I wanted until tomorrow, and nobody else had replied -- if THIS post was made 24h AFTER the above post, then it would NOT be a double-post, even though I replied to myself.
but because I am replying to myself in LESS THAN 24HOURS, it is a doublepost.
Also, it is NOT a huge deal, only a minor annoyance on the forum. THat's why the "warning" is stated as a "gentle reminder". You will not get in trouble for doubleposting unless you do it a lot, and even then, I will just say "Okay, look, you've got to learn, silly". Stop worrying about it so much please
