Everybody, I responded one of the discussions here, unfortunately, there's something error appears on my screen when i clicked the submit button then I thought to respond again on the same discussion since I haven't read my reply on the thread. Until few minutes upon restarting my browser then log in here again, I checked that discussion and then I saw my two replies in a row in the same reply, everyone might think I am spamming so I want to delete the second one I posted but found nothing a delete button. How to delete it? thank you
