> First I used asterisks (*), then the underscores (_), and then I used the option at the top of the post editor, and THAT didn't work either.

*Ahh I know the issue m'dear. I don't think the underscores work at all tbh- every time I tried to use them it would not work in the slightest. I had to figure this out myself- because you know how I always use italics for pretty much my regular chatting~*

*The thing is- for EVERY line break you have to complete the asterisks pair*

*So for my first line there is two (before "Ahh" and after "chatting"), for my second line there are two (before "The" and after "asterisks"), and this line has two as well*
