Answer:
Use underscores before and after the word. Type:
Oh _really_
for a try. :)
And for bold you do * before and after the word(s). For example: If you wanted this: "I absolutely adore junebugs." You would do: I *absolutely* _adore_ junebugs. Or if you want it bold AND italic : "I wished that I could fly really high! You would type: I wished that I could fly really _*high*_ :D
To cross out things like this: hi then u do -hi-
