the reason I was hesitant to do it manually is because the bbcode was starting to pile up like this
[ size=3 ][ font=Arial ][ size=5 ][ size=3 ][ font=Arial ][ size=5 ][ size=3 ][ font=Arial ][ size=5 ][ size=3 ][ font=Arial ][ size=5 ][ size=3 ][ font=Arial ][ size=5 ][ size=3 ][ font=Arial ][ size=5 ][ size=3 ][ font=Arial ][ size=5 ][ size=3 ][ font=Arial ][ size=5 ][ size=3 ][ font=Arial ][ size=5 ]Blah blah blah[ \size ][ \font ][ \size ][ \size ][ \font ][ \size ][ \size ][ \font ][ \size ][ \size ][ \font ][ \size ][ \size ][ \font ][ \size ][ \size ][ \font ][ \size ][ \size ][ \font ][ \size ][ \size ][ \font ][ \size ][ \size ][ \font ][ \size ]
and "SmileBASICs" is quite a long post so
but I removed it manually eventually, and weird things are still happening. Like look in the last section, and there will be links to images which used to having [ img ][ \img ] around them. I did not remove the img myself, they just disappeared after I edited the answers spoiler in the Quiz (still last section) for some reason
edit: fixed the pictures now
