I'll copy and paste something I wrote to another user:
Actually, if you look at the structure of any post in this forum, you can see your name, your status (Bohemian), buddy button, PM button, and another part where it says "Posted: 26 Nov 18, 10:07", etc.
Well, at the right of the date and time, there are three buttons (which you can still click but are hidden). One is for editing posts (the first one), I never used the second one so IDK what is it for, and the third one is for quoting messages. If you place the mouse over those hidden buttons, it even shows a description of what they do. Just in case you're unsure.
