I knew pretty much nothing about foruming when I joined.
But maybe I'm strange in that I didn't find posting below the final [/quοte] to be a complicated concept.
If the number of opening quote tags is greater the number of closing quote tags, it will automatically add a [/quοte] at the end, even if you put your text at the bottom.
(note: I changed the "o" in "[/quοte]" to an omicron so that it doesn't mess with formatting)
