Hola amigos! There's some cool ways to format text in these here text boxes what you are typing into. Highlight some text with ye olde mouse, and see what happens! A little box popped up and let me make all this text bold. I can also make text italic.
Then there are lots of other formatting options too!
(I made that a link by clicking the little diagonal arrow.)
These text boxes you type into use a cool little dingus called Markdown that lets you write HTML code without all the little < > and / and all the other things that make writing HTML code so bothersome when all you want to do is write and format some text.
