This is a list of a bunch of features I found that work in comments and descriptions! For them to work, simply put the "command" in between these things: <> and put one of those in the beginning of what you want to alter, and then put another one on the end.

b & /b = Bold!
i & /i = Italics :o
u & /u = Underline :)
s & /s = Strikethroughs...
h6 & /h6 =

very smol

h5 & /h5 =

a bit bigger, but still smol

h4 & /h4 =

a bit smaller than normal

h3 & /h3 =

a bit bigger than normal

h2 & /h2 =

a bit bigger, bit still not the biggest

h1 & /h1 =

the biggest!

That's all I have for now. If you find more, lemme know! I'll continue putting stuff here if I continue to find things :)

A bit more advanced things:

p style="color:red" & /p =

Change the text color!
