John,
No course required, IMHO. Print out this page:
https://www.electrical-contractor.net/ubb/ubbcode.html and try playing with some of the items on it.
Also, as you are looking at this text, at the top of this box is an icon for a sheet of paper with a pencil on it (the right hand icon). It is the "Edit/Delete Message" icon for my message. Click on it and you can see the way I inserted the link, above. Don't worry about hurting my message. Without my password, you can't hurt it.
