I'm just a silly billy who has lurked on Chapo.chat wink for quite awhile now; But I don't know how to do half the things (more like 90%) above the text box window that I put my delicately selected words into to make the freshest and most delectable word salads. So... How do and what do? If a power poster would like to go over each feature individually I shall abandon atheism and pray to satin for infinite 9/11's on the first world. Thx in advance. (this was going to be in regards to the emojis but thankfully realized that it wasn't just the lame ones you get on your phone when you click on the face, only if you don't search for anything) 
[ put the text you want here ] ( put the URL here )
Do that without the spaces between the brackets and the text to make your hyperlink.
OMG... I clicked on it and saw the link in my address bar before it finished loading, can't believe you've done this. Lol'd super hard though
But it's green on my end!?

Yus sorry it is green, for whatever reason I typed blue since that's the default for hyperlinks. Edited my comment after.
To quote, just slap a > at the start of a line, then a space, then insert the quote. I think you need to add a line break afterwards for it to work properly.
You can also hit the 'view source' button on a comment to view the text without markdown, if you're curious how they formatted the text. Per image below
Super helpful comrade.
I found a YouTube link in your comment. Here are links to the same video on alternative frontends that protect your privacy:
Good bot, will do next time.
