Don't worry newfag-sama, I'll help you.
Just copy and paste the link from the other thread into your post and it automatically converts it to the format. Also, it requires 2 >> in order to get it to link within the board.
Additionally, you can cross link to other boards by using 3 >>> followed by /boardnamehere/ then postnumberhere. Or, just post the link to the thread like before.>>114485441
