I "grew up" on HTML and only learned BB code here. The three features I found most helpful were the Standard (not WYSIWYG) editor that shows the actual tags being used, the Preview button that shows me what my tags will do, and the Reply with Quote button that lets me see what tags someone else used to produce a particular result.

You can select the editor you want to use from Your Control Panel >
Edit Options. Scroll down to Miscellaneous Options > Message Editor Interface.
