You didn't even have to hit the reply button twice. I posted in a couple different threads and the single button press resulted in two copies of the post so I had to go back and delete the dupes. A couple other times, it didn't post duplicates but did produce the "you have to wait N seconds before posting" message even though I had only clicked "post reply" once. It was pretty funny, actually.Lol, this site is a little glitchy today. It seems like the reply button isn’t working, causing folks to hit the button multiple times.
